This is based off the common cereal dry box, desiccant box, sled……. thing see photos. I like the design and have great luck with it until I tried certain rolls of filament like Sunlu. Sunlu is great filament however it seems the edge of the spool is beveled in such a way that it keeps trying to get in between the bearing and the sled chassis especially a full roll. I edited this bearing to have a lip on the inside to prevent the spool pinching. please look at all clearances and tolerances before use it works for me and seems to work well your results may vary. SEE photos for details:
left bearing in photos is old version, right bearing in photos is new, and middle photo is an example of spool pinch.
