Anybody still have the STL for the old X-Carriage before the rack and pinion setup?
Is this what you looking for?https://github.com/mjrice/wilson/blob/master/stl/alts/x-carriage.stl
That version is for the Wilson which uses 8mm rods unlike the Wilson II which uses 10mm ones. I know there was a Wilson II one when it had the servo mechanism but the archive for it is gone now.
From the Wilson2 project you can browse commits and select earlier versions of the project. I selected one from before the rack and pinion commit and found an x-carriage that may be the one you are looking for.
That is exactly what I was looking for. I tried the history but must have done something wrong. Need to work on my github skills.
