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.

27/01/18 - Added a second type of joiner with a filament guide and a way to avoid using the nuts and metal rod

2x 10mm ID 26mm OD Bearings
2x M10 Nuts (or 4x if you want nuts on the outside of the rod as well) - Optional
120mm Length M10 Threaded Metal Rod - Optional
