Startt / Tronxy-xy100 X-axis Mod

thingiverse

I've created Prusa i3 mk3 inspired x-axis parts for my Startt printer. Belts are tensioned by the X stepper tilt, with adjustment made possible by an extra screw that pushes against the mounting screws. There are two versions of the idler side part: the x_idler_v3, designed for a 5mm id and a 6mm wide bearing idler; and the x_idler_v3_3mm, created specifically for a 3mm id and 9mm wide idler pulleys (T16's). All mechanical components - rods, bearings, and the x carriage - have been transferred directly from my Startt printer. For motor mounting screws, I recommend using ones that are at least 17mm long. Additionally, you'll need an M4 x18 (or longer) cap screw and nut for the tensioner. In some cases, a slightly longer belt may be required, depending on how your original one was cut.
