After going through multiple spool holders, I gave up on them all and came up with this one.
- Ball bearings make for smoother spinning (and less wear on your extruder!)
- Using only two bearings, and (more importantly) keeping them at the center means MUCH smoother spinning
- M10 bolt easily mounts to almost anything
- Fits Prusament, other spools up to 51mm inner diameter
Printing
- PLA or PETG
- No brim or supports
- 15% infill
- 0.2mm layer height

Assembly
- Print 2 of this model
- Use a M4 bolt to push each M4 nut all the way through each model's hex hole
- Push the M4 bolts through each round hole, and screw tightly into the M4 nuts
- Press the ball bearings into each side of the assembly
- Firmly attach the M10 bolt to a shelf (bolt - shelf - spring washer - nut)
- Slide the assembly onto the M10 bolt (bolt - spool washer - assembly - washer - nut)
- Gently tighten the nut
- Slide your spool over the assembly
- (optional) I use a little spring clamp to avoid drift
- To change spools, just remove the spring clamp
