This is a remix of the Prusa i3 Rework X-carriage by eMotion-Tech (thing #119616) to which I have added the standard 30mm apart holes for M3 screws and nut traps for a Wade's extruder found in many Prusa i3 variants. So now this X-carriage accepts not only all the extruders designed for the Prusa i3 Rework, but also most of the extruders designed for other Prusa i3 variants.
I have actually verified that the four LM8UU linear bearings provide more stability vs. the usual three bearings in the standard Prusa i3 X-carriage. Also the carriage itself is very well designed, looks good, prints easily and the teeth for the GT2 belt are perfectly defined. I also like the fact that there is a small separator between the LM8UU bearings, so they don't rub against each other.
I intend to use this new X-carriage with the P3Steel version 2.01 variant that I am assembling to achieve higher printing speeds.
OpenSCAD sources are included but need the X-CARRIAGE.stl file from eMotion-Tech to compile.
