About this 3D model

It fits the standard x-carriage of Prusa i3 Vanilla repo. I also added a few pieces that help to avoid warping (using no brim), easy to remove. There's also a spacer useful if you use standard NEMA17 4.8 kg/cm motors to increase the distance from the frame to the motor itself. Based on misan's Greg Extruder (use his gears and idler/washer)
