Made by FRC 5254 HYPE.
A 775 style motor "gearbox" that clamps onto either 1x1 or 2x1 tubing and allows a reduction using a GT2 Belt. A variety of pulley/belt sizes can be used due to the sliding tension bearing in the middle.
There are two versions of the sliding bearing mount depending on the tolerances of your printer.
2" Tubing: follows the spacing of a VEXpro single reduction clamping gearbox.
1" Tubing: follows the spacing of a side bearing gusset
