Works for the muscle rack or home depot husky shelves. use in junction with with my filament dispenser for the same shelving system. The bypass pulley is for abrasive filament, as the infiniti flow gears are not hardened. Works great, both the bypass pulley and the infinity flow in this format. Gets all the filament up out of the way.

Requires the hardware the infinity flow comes with and some 5/16 bolts: 2- 1.5" 1 - 2" Print the the whole thing without the "Precise outside walls" selected. the bolt for the pulley should be a bit hard to put in.
