Slide bearing and sleeve for filament spool

thingiverse

Came up with this as a fix after noticing the Fiberflex spool began rocking back and forth during printing. This caused "tugging" of the filament, which had to be stopped immediately. The solution is a simple slide bearing because I couldn't fit any rolling parts inside due to the large inner diameter combined with a small outer diameter. To reduce friction, lube it a bit with some kind of thin lubricant if necessary. The tolerance on the bearing is 0.2mm between the inner and outer part. Key dimensions include: Bearing outer diameter: 48mm Bearing inner diameter: 24mm Bearing height: 16mm Sleeve outer diameter: 50-52mm "wedge" shape Sleeve inner diameter: 47.5mm for a snug fit, which can cause problems if printed with non-flexible filament Sleeve height: 18mm
