MMU2S rewinding

thingiverse

To build this project, you'll need a few key components: rubber string and two bearings of specific dimensions. The bearings are 22mm in outer diameter (OD), 8mm in inner diameter (ID), and 7mm in width (W). To secure the rubber string in place, apply tension by twisting it slightly. In addition to these components, you'll also require two M3 screws: one with a length of 30mm and another measuring 25mm.
