Spool Roller

I upgraded this design because I didn't want to place it on top of my printer initially. The original can be found here... https://www.thingiverse.com/thing:1635585 The modifications I made were primarily tailored to match the size bearings I already possessed, rather than purchasing new ones since I had a large collection. The bearings feature a 5mm center diameter and an outside diameter of 15.5mm. Bearings are also press fit, allowing you to choose whether or not to print the caps.
