Genealogy / Archeology of the Prusa i3 X Motor End
In this page I will illustrate (to the best of my knowledge) how the original design for the Prusa i3 X Motor End printed part has been used (and has evolved) through some Prusa i3 variants. I have researched the evolution of this particular printed part - the X-axis motor end for the Prusa i3 - because I wanted the best possible design for my P3Steel.
I was surprised to find that in some cases the GPLV3 license under which the original design by Josef Prusa was released, was not exactly respected. This has the unfortunate effect of halting further development - or at the very least making it much more difficult - of a particular "evolutionary branch" i.e. we reach a development dead-end.
Enough preliminaries and let's see what is going on:
1st Gen: Josef Prusa's original design

2nd Gen: Misan's mods
Misan (a well-known Spanish developer) added a few improvements to many of Josef's original printed part designs and made his OpenSCAD sources freely available, mainly on Thingiverse:
