Assembly of an MK8

Preamble

There are an awful lot of cheap MK8 extruders, and their derivatives (close and not so close), out there – with different number of parts, different bolts (lengths and thicknesses), screws, washers,  varying arm designs (enclosed or non-enclosed bearings), etc.. However, not many assembly instructions. So I’ll ramasser a few different assembly pictures here.

This post was inspired by How to build the extruder motor holder for the Kossel Mini

From [Improved Version] YOTINO Right Hand MK8 Remote Bowden Extruder Accessories 1.75mm/3mm Filament All Metal Remote Extruder Frame Block for Reprap 3D Printer Kossel Prusa, note that the bearing is enclosed, with a flange either side:

A great guide from RepRapWiki – Extruder Assembly, shows a the assembly process in detail.

A lot of the parts vary, this has three washers that others do not have, from 3D Printer Makerbot Mk8 1.75mm Filament All-Metal Aluminum Alloy Bowden Extruder:
