Prusa Core One Ball Bearing Spool Holder

I have printed several of the available ball-bearing spool holders for the Core One. While they functioned flawlessly, I found that the holders protruded too far from the printer. This would have prevented Haasi's upgrade ( Prusa Core One Drybox Upgrade ) from being installed without modifications. Therefore, I had to come up with my own solution and designed my own spool holder. The original Prusa spool holder projects 80mm; the upgraded, ball-bearing version projects 84mm.

In addition to the printed parts, you will need the following to complete the assembly:

- M8x70mm Socket Head Cap Screw (1) - M8 Flange Nut (2) - 2x 8x20x7 Ball Bearings (608) (3) - 4x M3 Threaded Inserts

The completed base without the spool body should then look as follows

I hope this upgrade can help others in the community who may have a similar issue.

Stay tuned for more innovations, and happy printing.

Until the next print,
