DoomMeister's, Kuehlings Sells/Prusa X Ends

thingiverse

I've been working on enhancing my Mendel using linear bearings, smaller pitch belts, and proper lead-screws. During this process, I noticed a few things: 1) Prusa (iteration 2) X ends don't fit the Mendel design as the distance between the Z axis and lead-screw is actually 30mm instead of 29mm. This was a surprise after printing a set. However, I think the belt-driven Z lead-screw design is superior to the dual motor one, so I'll be sticking with it. 2) Many x-axis designs for trapezoidal (ACME) lead screws utilize metal nuts, but as evidenced by my old Z screws and the iron fillings in my Orca's Z screws, this is not a good idea. 3) Editing Prusa SCAD sources can be quite frustrating. As a result, I modified Jonas Kuehlings' Improved X ends for Prusa to accept a plastic lead-screw nut, which can be machine or print-based. The Z nut press fits into the holder (use an 8mm bolt to help) and is secured with a key bolt. I separated the Z Nut design as a separate thing since I prefer to use GPL for my projects, and the base design is CC-BY-SA. Files are available for both Sells and Prusa Mendel configurations.
