Top Rail Filament Spool Holder Ender 3 / Cr-10 Series (2020 mount)

thingiverse

I designed a spool holder that slides onto the 2020 top rail with ease. It comes equipped with holes for screws, although I've never had to use them myself. My printer has trouble printing threads in thumbscrews, so I've been using a 1/4-20 tap to chase the threads instead. The tension on the rolls can be adjusted by tightening the thumbscrews, and it works best when there's just the right amount of tension to keep the spool from unwinding too far. To build this spool holder, you'll need: Four pieces of 6900ZZ 10 x 22 x 6 mm Deep Groove Ball Bearings Two pieces of 1/4-20 x 2.9 in. (75mm) threaded rod (all thread) This project was uploaded on November 2, 2019.
