Bearing Spool Rollers

thingiverse

I was dissatisfied with the operation of heavy spools on fully printed spool rollers. The spools consistently failed to run smoothly. I've designed a new set of rollers that can accommodate proper 608-2RS bearings inside to enable the spool to roll as smoothly as possible. The shaft for the bearings is one continuous piece, so you'll need to pause the print halfway through to add the bearings. Setting a simple timer for ten minutes was sufficient to remind me, but you could also incorporate code to halt the process.
