Filament spool Bearing (& lock)
Description
This is a TinkerCad Special. Very simple bearing for the spool to sit on to help it spin on the spool holder instead of being high centered causing tension. The dimensions are rough so I imagine it should fit a lot of overhead spool holders, no promises. The outer diameter is about 2 and 3/4 inches. The inner diameter is about 1/2 inch. I printed this with 4 walls and about 5-10% cubic infill but feel free to use whatever suits you. You might notice its low poly but because it doesnt need to be an exact fit it doesnt matter. After putting this on I didn't feel like there was even a need for another filament guide because the roll is able to spin so much more freely. The lock is simple and should help keep the filament from falling off the spool holder.Its nothing fancy, just clip it on and let it hang.
