Kits and Parts
The complete kit from MJRice is Reprap Wilson II complete 3D printer kit, $485 (฿16,703.40 THB)
Reprap Wilson II 3D Printer Required & Recommended Wilson2 Printed Parts, Newest for $69.99 + $16.00 (p + p) (£54.57 + £12.48 (p + p)), approximately £67 in total. 38 pieces.
Kit Reprap Wilson II 2 3D printer PLA + ABS Proteinas Reprap Printed prusa i3, €59.99 (£51.11) + €25.99 (p + p to Thailand) (€24.99 (p + p to the UK) (£21.06)), approximately £71 in total. 39 pieces.
Note: There are some important differences between the HTA3D and 3DPrinterHut printed parts:
- HTA3D uses ABS for the non-structural printed parts, and PLA for the following structural printed parts, which form the frame, for enhanced rigidity:
- HTA3D has reinforced certain parts of the structural printed parts, such as:
- L brackets (which have a diagonal infill)
- Z axis motor mounts
Whereas, 3DPrinterHut only offer the parts in white and in ABS (no PLA), without the reinforcing.
In my opinion these differences make for a superior build when using HTA3D’s parts, so well worth the additional £4.
In order to get some quotes for the parts if sourced locally, in Thailand, I fired off this email to a number of 3D shops around Bangkok, which are listed above,

When a 3D print requires to be very strong, Nylon is a good option. It usually prints in white and is available in different formulas. Taulman, for instance, makes Nylon 618, Nylon 645 and Bridge Nylon, which apparently has great bridging capabilities. Nylons print at a relatively high temperature (245 – 250 degrees Celsius) but – contrary to what you might think – print odorless.
Polyamide, also known as Nylon, is a popular synthetic polymer used in many industrial applications. With nylon 3D printer filament, you have a cost-effective plastic that’s strong, light, flexible, and wear resistant. It’s also less brittle than PLA or ABS. Also, it’s stronger and more durable than the two.
Nylon 3D printer filament can be used in a variety of applications. They include machine parts, containers, tools, consumer products, and toys. Oh, and another thing: you can use fabric dye to color it. 3D printing nylon is relatively easy if you keep your spools dry. Otherwise you can run into problems. Since Nylon filament quickly absorbs humidity from its environment (in less than one day), it should be protected from humidity while in storage.
But it doesn’t stop at that. 3D printer filament manufacturer Taulman has developed different types of nylon filament. Depending on the intended application of the 3D printed object, it is up to the user to decide which variation is most suited.
- Taulman nylon 618 is an industrial grade material. It is great for prototyping but also for end products. Basically, what sets nylon 618 apart, is it’s excellent layer bonding if printed at 245°C and all the other settings are set appropriately. Also, nylon 618 does not emit any fumes. What might look like fumes, is water evaporating during printing. This type of nylon can be machined after printing and can also be used as the material for casting molds since it is possible to 3D print a very high quality, chemical resistant, and airtight object. Note: Glass and aluminum surfaces are not suited as print beds for nylon 618. Instead, a rougher or fibrous material like unfinished wood or Garolite should be used. Here is a list of detailed usage guidelines and material specifications.
- Taulman nylon 645 is an improved version of nylon 618. Although mostly identical, nylon 645 has even more tensile strength and even better layer bonding. It is a translucent material unlike nylon 618, which is opaque. Here is a list of detailed usage guidelines and material specifications.
- Taulman Bridge nylon is a less costly version of nylon 645 spec nylon. Developed following the requests of a wide range of customers, Bridge nylon still meets certain desired characteristics such as excellent tensile strength, better first layer adhesion, affordability, reduced water absorption, opacity and reduced shrinkage. Click here for a list of detailed usage guidelines and material specifications.
General nylon 3D Printer Filament Properties:
- Primary benefits are high strength, durability, and flexibility
- Ideal for mechanical components, structural parts, gears and bearings, and dynamic loads
- Tends to have a glossy finish
- High durability

- Not soluble
- Can by recycled
- For food safety, refer to manufacturer guidelines
- General print temperature range is 220°C – 260°C
- Must be dried before 3D printing
- Some shrinkage during cooling
- Heated bed at 50°C – 100°C recommended
- Printing difficulty is moderate, requires fine-tuning of bed and nozzle temperature
From 3DPrinterHut, Reprap Wilson ii 3D Printer Nuts & Bolts Fasteners Set – Wilson2 Screw Full Kit, $35.49 (£27.67)

HTA3D supplies Tornillería para Wilson (Wilson fasteners), for €18.99, note not specifically Wilson II, so there will be some differences.They will supply a partial kit of the Wilson II,
which is missing, the following:
- 2 x M3 x 60mm machine screw, These are used for the extruder
- 9 x M2 x 16mm machine screw – These and M2 nuts for mounting end stops, 1 for servo mount, and 2 for LM2596 mount
How does that compare with a bulk purchase of T-nuts and brackets in the UK? The price is about the same for the brackets. A bulk of 100 T-nuts is about £11, see for example, Drop In T-Nut M3-M6 Thread For T-slot Aluminum Extrusion 2020 11×10.2mm, £11.59 for 100 x M5.
The price of extruded aluminium, in Bangkok, is about 40% of that in the UK, so you are looking at around £18, as opposed to around £40.
Again from 3DPrinterHut in China, on eBay, 1Set Wilson ii 3D Printer 2020 Aluminum extrusions Wilson2 T-slot Profiles, $61.78 (or $58.69 on offer) (£45.76)
For just £38 for 4 meters, in the UK, 2020 Aluminium Extrusion Slot 6 Profile 20mm x 20mm – 3D Printer & CNC – 20x20mm from wedo3dprinting. Or for £38.37, Aluminium Extrusion Slot 6 Profile 2020 20x20mm for CNC 3D Printer Jigs Frames from it_tech_uk.
However, I had some issues locating a supplier for 2020 aluminium. I found a supplier behind MBK, in the Pathum Wan/Chula area, P.M. Metals & Tools LTD., Part., 163/2 Charoen Mueang Road, just off Banthat Thong Road (the number 73 bus passes within 50 m of the shop), which had some 2020 extruded aluminium at 750 baht for 6 meters. However the profile of the aluminium was not exactly correct, as it will not accept T-nuts, and uses regular M5 nuts instead, which would be fine but not perfect. The stress of a tightened nut would not be distributed so evenly, and over a lesser area. However, as the mantra is tighten, but not too tight, then these extrusions should suffice.
They also sell 2525, 3030 and 4040 and 4080, but not 2040.
The owner, Prachak, and his son (Ger) are very helpful and are interested in 3D printing projects.
Ban Mo was the only place that I found supplying the correct extrusion. One shop (Thai Robo Shop) on the second floor (south end of eastern corridor) of BanMoh Plaza had it at 250 baht a meter, and another in a parallel corridor (North end of Western corridor) for 200 baht. The first shop supplied inner brackets, bolts, T-Nuts and washers for 50 baht.
There is also another shop selling the correct extrusion, and it is along Banthat Thong Road. However, to date, I have been unable to locate it.
Cutting to length
However, getting it cut to the correct lengths is another matter. The shop that sells the 6m lengths, in Charoen Mueang, had a cutting machine.
I could attempt to cut it by hand, although I am reluctant to do so, as I think that the finish will not be terribly good.
I went to a local metal workers, where the guys offered to cut to length for 120 B$. However, an angle grinder was used, on a small jig. Predictably, upon cutting the first 500mm lengths, the finish was so rough, and the lengths were no equal that I cancelled the work. See the results here:
Another machine shop offered 200 B$, but again they had no visible cutter, so I was reluctant to destroy even more aluminium.
A machinist that looked very competent wanted 700 baht to perform the cuts, 100 baht per cut. This was almost as much as the aluminium had cost in the first place! Also, for 700 baht I can go to Charoen Mueang, purchase a new 6m length (with the incorrect profile) and get the pieces cut for free!
In the end I went to the shop in Charoen Mueang and got the pieces cut for 90 baht – however, the owner was there and took pity on me and did it as a favour. It is not a service that they wish to provide. However, he does stock 2020, albeit, as mentioned above, with an unusual profile.
I got the aluminium cut, in the following way:
1. To maintain a clean cut, at least at one end, I ensured that the 500 and 400 mm lengths were cut in such a way that the original laser cut, and finished, ends were part of the length – that is to say the cuts were measured from the ends, rather than from where the previous new cut had been.
2. The one meter length than had been badly cut in half had it’s two (approximately 498 mm) lengths cut down to 400 mm, whilst retaining the original laser cut and finished ends.
3. As it is not possible to obtain to 500 mm lengths from 1000 mm of aluminium, a 500 mm and a 400 mm length was taken from a 1000 mm length, with 100 mm as wastage. This was done for two lengths of 1000 mm.
4. The three 300 mm ends – two of them retained the original laser cut and finished ends. After the third “middle length” had been cut then a small simultaneous shaving was required of all three lengths to make them the same length.
As the design of the Wilson II is scalable (source: RepRapWiki – Category:Wilson)
…the design has a parametric build area, meaning it is relatively easy to scale the X, Y, and Z axis within reason.
I did wonder whether the extruded 2020 aluminium with the non-ideal profile, at 6 m for 750 baht, would be a good idea, and what maximum size I could obtain.
Aluminium Extrusion Corner braces/brackets
In Ban Mo, ThaiRoboShop sells them (with 2 x M5 bolts, nuts and washers) for 50 baht. The corner shop, SangTaWan, (Ban Mo and Thip Wari Alley) sells them for 45 baht, and, in fact, the shop owner discounted them so that I got 6 for 240 baht.
Right Angle Inner Outer Bracket T-Nut Screw for 2020 Aluminum Extrusion Profile, £3.99 + Free for 4 pcs. (£5.39 for inner brackets) UK/EU only.
From HTA3D, Kit de varillas para Wilson, (Rod kit for Wilson) €19.99, offers smooth and threaded rods.
The leadscrews required are:
- T8 300 mm x 2
T8 lead screws (with a lead of 8 mm) are available individually, from HTA3D:
I looked around Ban Mo, and the prices were between B$400 – 450 for 300 mm.
On eBay, there are a number of cheap T8 leadscrews with a 8 mm lead:
- The cheapest supplier was on eBay, from China, 100 – 600mm 3D Printer T8 8mm Rod Lead Screw Nut Z Axis Linear Rail Bar Shaft, £3.59
- Cheaper still, 3D Printer 8mm Lead Screw Rod Z Axis Linear Rail Bar Shaft Golden C8S9, £2.86/3.91 for 300/350 mm. However, not only they do not appear to ship to Thailand, but there are also some serious communication difficulties. I seriously do not recommend this supplier, tydy98.
- 3D printer THSL-300/400/500-8D Lead Screw Dia 8MM Thread 8mm with Copper Nut SHR, £2.88 for 300 mm, and they ship to Thailand.
However, an 8 mm lead is not as precise as a 2 mm lead. From Accuracy vs Precision and Threaded Rod vs Leadscrews in 3D Printers:
In general, FFF/FDM printers use relatively infrequent, small, precise movements on the z-axis and consistent, fast movements on the x and y axes. A single start leadscrew with the tightest pitch possible (highest thread density, smallest pitch) is generally going to be your best bet for the z-axis, while you may or may not need something a little steeper to get the speeds you’d like from your x and y axes. While this may seem somewhat arbitrary given the precision of movement you can get from a stepper motor, an important factor to remember here is torque.
A more aggressive leadscrew will require more torque to drive. We have one kit printer we bought a couple years ago that has an overly aggressive multi-start leadscrew for the z-axis. The small motors included in the kit do not have the torque required to reliably start upward movement of the carriage, leaving it sitting there skipping steps until the carriage is given a little upward nudge to get it going (no, it’s not a lubrication issue or a driver that needs turning up).
So, a 2 mm lead is preferable to a 8 mm lead, as not only is less torque required, but also more precise movements are obtainable.
- This supplier, 8mm Lead Screw Rod Z Axis Linear Rail Bar Shaft+T8 Nut For CNC 3D Printer Reprap, offers both 2mm and 8mm lead, for £4.98 and £5.38 respectively, for 300 mm. For 350 mm, 2/8 mm costs £5.28/5.58. This appears to be the cheapest supplier.
- Slightly cheaper, 8mm Threaded Rod LeadScrew Mounted Ball Bearing T8 Nut F 3D Printer ACME Stepper, $5.58/5.98 (£4.31/4.62) for 300/350 mm respectively, with a 2 mm lead. However, the T8 Nut is not included in the price, which costs an additional $1.89 (£1.46), or £0.99 from 2mm T8 Start Lead Screw Nut Brass For CNC 3D Printer Parts Printer Z Axis
There is a leadscrew with a 1 mm lead available, but it is much more expensive than the leadscrew with the 2 mm lead, T8 Pitch 1mm / 2mm Lead 1/2/4/8mm Rod Stainless Lead Screw + brass color nut, £9.02/11.78 for 300/400 mm respectively. Note that from this supplier, the cost of the leadscrew with either a 1 mm and 2 mm pitch/lead, is the same. A lead of 1 mm is probably a bit excessive. Somewhat bizarrely, from the same supplier, lijieqion_0, there is a significantly cheaper leadscrew with a 1 mm lead:
- Copper Nut with T8 Lead Screw Dia 8MM Pitch 1mm Lead 1mm Length 300mm 1pcs, £5.70
- Copper Nut with T8 Lead Screw Dia 8MM Pitch 1mm Lead 1mm Length 400mm 1pcs, £7.44
It is unclear why it is cheaper – is it because the nut is copper and not brass? Or is one Acme/Trapezoidal and the other square?
It was worth noting that in both of the above cases, 600 mm length is available (see Copper Nut with T8 Lead Screw Dia 8MM Pitch 1mm Lead 1mm Length 600mm, £10.06), so you could cut one length in half for two 300 mm lengths. However, the lengths would be shorter to 300 mm, and you would need to purchase an additional brass/copper nut, which would add £1 to the cost, thereby resulting in a saving of only £1… isn’t it worth the additional £1, to save you having to cut it?
Anti backlash nuts
- 1 Set Anti-backlash T8 Spring Loaded Nut For 2mm Lead Screw Acme Threaded Rod, £2.35, for a 2 mm lead
- Cheapest, 1 Set T8 Anti Backlash Spring Loaded Nut For 2mm Acme Threaded Rod Lead Screws, £1.42 + £0.88, for a 2 mm lead
- For 2/8mm Lead Screw Trapezoidal Acme Threaded Rod T8 Anti-backlash Brass Nut, $3.73 (£2.89) for lead of 2/4/8 mm + Free p + p.
- New Brass T8 Anti-Backlash Spring Loaded Nut Set for 8mm Threaded Rod Lead Screw, £2.12, for 8 mm lead.
The smooth rods required are:
- 500 mm x 2
- 370 mm x 2 (The length of these is actually flexible and can range from 350 mm to 380 mm (340 mm min. and 390 mm max). See Reprap Wilson II Assembly Video series part 2 – v2 at @1:05 and @28:20)
- 320 mm x 2
A total of 2380 mm are required.
From HTA3D, Kit de varillas para Wilson, (Rod kit for Wilson) €19.99, offers smooth and threaded rods, but these are M8, and not used in the Wilson II, only the Wilson RS and TS. The 8 mm bars are also available individually, Varilla lisa calibrada diámetro 8 – Cortada a medida.
M10, 10 mm bars are available individually, from HTA3D. Two of each are required:
- Varilla lisa calibrada diámetro 10 – Cortada a medida
- 500 mm €4.95
- 370 mm €3.80
- 320 mm €3.45
- Total cost: 9.90 + 7.60 + 6.90 = €24.40 + postage €18.68/24.19 (to the UK) = €43.08
On Amazon, ARBUYSHOP 6pcs/set Reprap 3D Printer Wilson ii M10 Smooth Rods Wilson2 OD 10mm smooth rods,Linear Shaft Optical Axis chrome plated, but currently they are out of stock.
On eBay, there is this kit from China, 1set Reprap 3D Printer Wilson ii M10 Smooth Rods Wilson2 OD 10mm Linear Shafts, US $54.34 (£41.96), free postage. Whilst expensive, it does come with the important note:
Description:Our 10mm Linear Motion Precision Ground Hardened Steel Shafts are perfect for RepRap 3D Printers when used in conjunction with linear bearings. For smooth and wear resistance motion linear bearings require linear shafts with a Rockwell Hardness greater than ~52Hrc. Most Stainless Steel Rods are not suited for linear motion applications, because of this we have sourced Gcr15 Hardened Steel Shaft with a Rockwell hardness of 60Hrc.This set is for wilson ii use. If you need other parts for wilson ii printer use, please search them in our store or contact us. we are more than happy to help.Guide Length: 370mm/500mm /320mmDiameter: 10mmMaterial:Gcr15Hardness:60+-2Grade:G6Roundness:<0.01Surface finish: 0.3-0.5Straightness:0.15/1000mmSmooth rods for Wilson ii Frame: 2 x 370mm / 2 x 500mm / 2 x 320mm
These are precision linear rods meant for automation use, and have a hard chrome finish.
*6 pieces smooth rods including 2pcs 370mm / 2pcs 500mm / 2pcs 320mm length(10mm Diameter).
Sourcing the rods separately
In Ban Mo, Bangkok, the prices were 180(?)/250 to 280 baht/m, so half price the cost of the rods from HTA3D. However, it is not clear if these are smooth/chromed stainless steel. They certainly are not hardened. However, I managed to get 3 meters for 600 baht (i.e. 100 baht per 500 mm – even though the rods were priced at 120 baht for 500 mm and 250 baht for 1000 mm (note that it was cheaper, by 10 baht to buy in two 500 mm lengths than one 1000 mm length), from the shop, SangTaWan, on the corner of Ban Mo and Thip Wari Alley, which is stocked full of servos and rods, etc. I checked all of the rods with both new and second hand linear bearings to ensure smoothness in movement. I got two 500 mm lengths and two 1000 mm lengths. Even though I only required approximately 2380 mm in total, I figured that the additional 500 mm could be used for the P3Steel, as one of the M10 rods is slightly defective and the bearing sticks about two thirds of the way up, see P3Steel from Poland – A tale of despair, dismay and woe (however, upon investigation, that is an M8 rod, and so the M10 is not of any used on the Z-axis – 500 mm lengths of M10 are used on the Y_axis though, so the spare 500 mm length could be useful).
Cutting the rods to size
As the rods were in one meter lengths, I would end up with 260 mm and 360 mm waste cuts. In order to preserve, at least one nicely machined end, the rods will be cut in from the ends, thusly:
Alternate cutting scheme
In order to reduce the wastage, here is an alternative cutting scheme. Given that
- X-axis steel rods range from 340 mm to 390 mm
- Z- axis steel rods are fixed at 320 mm
For the X-axis:
At minimum 340 x 2 = 680 mm
680 + 320 = 1000 mm – this is too close as some length is lost in the cutting process
At maximum 390 x 2 = 780 mm – leaving only 220 mm of length which can not be used elsewhere.
For the Z-axis:
320 x 2 = 640 mm
1000 – 640 = 360 mm
So, one X-axis rod and two Z-axis rods could come from one 1 m length.
The remaining rod, at 360 mm, taken from the other 1 m steel rod would leave 640 mm which could make two more Z-axis rods.
To allow for length loss in the cutting process the lengths of the two X-axis rods could be 355 mm, and still be within spec.
The only problem is that the cut ends would not be smooth and may damage the LM10UU bearings.
In Hornchurch, UK, these rods are cheap, 10mm Stainless Steel Round Bar Rod 1000mm Long Grade 316, £3.50, but again, it is not clear if these are smooth/chromed stainless steel.
On eBay, steel rods seem to be rather overpriced:
- Stainless Steel 304 Round Solid Metal Rod Bar Dia 3-14mm Length 125mm-500mm, £6.04 for 500 mm M10
- STAINLESS STEEL(304)ROUND BAR/ROD 4,5,6,7,8,10,12mm diameter (in many Lengths), £8.25 for 300 mm M10
Smooth rods being the point to note. For 8 mm:
- 30-40cm 8mm Chromed smooth Rod steel linear rail shaft For CNC 3D printer Reprap, 300/350/400 mm for US $3.97/$5.03/$5.80 (£3.07/£3.88/£4.48)

The LM10UU linear bearings are available individually, from HTA3D:
- Rodamiento lineal Lm10uu, €1.10
However, they are much cheaper on eBay, as I had obtained 4 for £2.20 when building my P3Steel:
- For 4, Steel 4X Inscribed Circle 10mm LM10UU Bush Bushing 10x19x29mm Linear Bearing JK, $3.75 (£2.88) (£0.72 each)
- For 10, NEW LM10UU 10*19*29 mm Linear Ball Bearing For 3D Printer CNC Machine 10Pcs, £4.31 (offer, normally £4.59) (£0.459 each) – it is best to buy two of these packs.
- For 12, LM10UU 10mm 12pcs Linear Bushing Ball Bearing Bush 10x19x29mm for Shaft Rod, £7.41 (offer, normally £8.23) (£0.61 each (£0.685))
One upgrade could be to use L10LUU:
The cheapest are about twice the price of the L10UU, see 1Pcs LM10LUU Long Linear Motion Ball Bearing Bushing 10mm Shaft DIY CNC Motion, US $2.49 (£1.93)
Another good upgrade, which again cost about twice as much as L10UU, would be to 12 Igus Drylin tribological LM10UU replacements, or LM10LUU (however, the LM10LUU equivalents are hard to find, if they exist at all).
Some examples of these LM10UU bearings, called Igus Drylin, are:
