The idea of building a Kossel came to me after:
- Seeing on ReprapWiki – Kossel, that the Kossel uses OpenBeam, which is very similar to 2020 extruded aluminium, except that it is 1515, and as I had already sourced some inexpensive 2020 for my Wilson II 3D printer, in Bangkok, it would not be much of a problem to go and get some more;
- Coming across HTA3D’s Kossel printed parts, on eBay, for €29.99, and;
- Having watched the following video on the Micromake 3D printer, that uses 2020 aluminium and is similar to the Kossel (inasmuch as it is a Delta printer). See this explanatory video:
However, as I have stated above, the main reason was that I had the idea of sourcing the aluminium for the Kossel, whilst I was in Bangkok, as aluminium is relatively cheap in Bangkok, when compared to Europe.
