There seems to be an STL issue with “Inner Shell”. please check if m3 heatset holes are blocked. Bambu and Orca slicer seem to not have this issue, but Prusa slicer does. Printables model viewer also has this.
These filled holes can be cut out with a negative modifier if needed.
Mounting holes: hexagonal shape. 40mm from center, 40mm hexagon edges, 3.2mm diameter ^ Mounting pattern on both sides
Height: 30.5mm +-0.5mm diameter: 142mm
The belt is inverted, with the teeth gripping the outside shell.
Tips & Advice
Use a small amount of lubricant on the smooth side of the belt
Print outer shell with a 0.2mm nozzle. I had to re-print my outer shell at 100.05% scale for the best results. Increases the size reduces friction, but also allows the belt to skip more
The logo can easily be removed by sinking the outer shell into the bed by 0.3mm
Assembe rollers individually, heatset the inserts, attach all rollers (use removable threadlocker if needed), insert motor, attach aluminum pulley on motor, attach belt and tension, place large bearing over the aluminum pulley, carefully install the outer shell (make sure that it doesnt push the belt off the rollers)
I printed the outer shell with 1 layer of black petg (on a carbon fibre build plate), then the rest with Prusament orange
