Spool Roller (NO SCREWS)

Spool holder for generic spool sizes.Used skateboard bearings (608zz).NO SCREWSNO NUTSUse offcuts of generic 1.75mm diameter filament as lock in pins. some may not need them if they are a tight fit.Everything is designed to be a very tight fit, ensure printer and filaments are calibrated.If you need a larger tolerance let me know and I may be able to create a model.FYI:Ensure filament used as the filament pin is not brittle as it may break and become stuck.If needing to remove the filament pin pliers are recommended for easy removal.I recommend making the filament pin slightly longer than the base for removal. Check out the model on my Printables.
