Another filament spool roller
thingiverse
I came across a stash of small ball bearings that I had ordered a long time ago. Since they wouldn't work in my other projects due to the incorrect size, I decided to repurpose them by building this filament spool roller. Here's what you'll need: 4 x ball bearings measuring 13.5mm/6.3mm/5mm (I'm not sure what their official name is) Simply print out the parts, remove any excess support material, press the ball bearings into place within the axles without needing glue, and then snap the axles into the ground plate. You're now ready to roll... literally!
