Prusa MK2.5S/MK3S X-carriage Split-Back Mod

thingiverse

This is the Prusa MK2.5S/MK3S x-carriage back with the following modifications: - back is split into two pieces - removing the top piece allows easy access to the x-axis belt - the bottom piece has a slit in the cable hole, allowing easy cable assembly/disassembly - the x-carriage adds two nuts I made the alterations on the original openscad designs from the prusa3d github https://github.com/prusa3d/Original-Prusa-i3/tree/MK3S/Printed-Parts/SCAD . Some of the original SCAD code drove me nuts, so I edited those too. Note that the bearing and polyholes scad files are Prusa's dependencies. The main advantage this has over the Prusa R4 x-carriage, is the ability to re-cable parts of the extruder easily. Unfortunately, with the Prusa R4 revision, there are insufficient screws available to the back cover to allow for a simple back cover replacement. The x-carriage had to be modded for placement of two extra nuts (where the extruder screws are).
