This is a Y-axis belt tensioner for the MendelMax 1 / 1.5, using a 16-tooth GT2 pulley and an M3 bolt.
I designed this because the original MendelMax Y axis idler/tensioner and every other design on Thingiverse (to date) all use a 608 bearing, which poses two problems:
- The smooth bearing causes backlash because the toothed side of your GT2 belt should not be on a smooth bearing.
- The radius of the bearing is much larger than the radius of the GT2 timing pulley you probably have mounted o
