Pantheon Design Spoolinator

A self centering spool roller system for use with Rubbermaid 5L dry goods containers, or (Everyday Essentials 5L cereal bin from Superstore if you're Canadian). The only other part you need are 608 skateboard bearings. Assembly video is available here https://youtu.be/SCglCylT2F0. The design is based on the principles that keep train wheels centered on the rails, and we like them because you can just drop spools into your containers , and they keep the spools centred and off the container walls.

Forgive us for the bad visuals. I was experimenting with filming on a cheap web cam.
