I needed a simple spool holder that clipped to my drawer along with a bearing roller. There is a cylinder that you can screw to the inside lip to keep it from rotating.

Once I made the roller, it was a little too free and was prone to rolling forward and having the filament fall off the spool. I made a TPU nut at the end where it provides some resistance.

Print one part each as in the STL, other than the Bearing Shaft, you'll need 2. See the attached image for assembly. The standard nut is there if you want free movement.

There's also a TPU end cap for rolls that have a solid cylinder as a center core. Just pop it over the end and it'll create a flat channel to sit in.

Requires:

• ¼" Carriage or Lag Bolt, minimum 3"
• 2 x 608 Bearings of any type
• #6 1-½" or M3 45mm screw.
