Description

This part can replace the rubber roller of the foldarap. My rubber roller doesn't wheel smoothly. So I prefer replace it with this printed part to reduce the friction between the filament and its drive idler.

Instructions

If you want to change values of the openscad parameters, check the SVG file. It contains a clear description of these parameters.
I printed half day with it without issues. Let's see how it lasts!
