Zero Resistance spool holder

Designed to fit on the Tevo Tornado control box but you can just stand it on a table if you want.

My take on a spool holder, I try to throw a bit of aesthetics into things that serve a functional purpose.

If it's too slippy, you can add a bit of resistance by tightening the nuts against the bearings but mine works just fine.
Requires a few other parts.
