[Anet/Prusa i3] Y-Axis improved belt roller

thingiverse

Improved end bearing and roller on Y-axis. My original setup had only one 608 bearing (22mm x 8mm) supporting the spinning belt. On the other side of the printer's stepper pulley is a 12mm diameter component. This part utilizes the same holes and screw as the original, but incorporates two 608 bearings with a custom 12mm roller axis. There are two versions: V3 and V4. The V3 design is the original, however it tends to fail (shear out) for me. I've created a reinforced V4 version that features a larger screw and nut inside, which provides significantly more strength. P.S. This part must be printed precisely as displayed in the slicer - vertically, with supports.
