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.
Orient the rollers and axles vertically, and the base on it's widest face, as shown in the photo of the print bed

We recommend printing in PETG as the parts need some flexibility. The rollers have a directionality. The tapered fat roller is the "front", so if you find that your spool is not being centered, flip the rollers around.
