A spool holder with ball bearings to replace the original Ender 3 spool holder. The filament bobin is positioned between two cones which provide correct centering. Two 608 ball bearings provide smooth filament movement.

 

Hardware needed:

 

608 sealed bearing - 2 pc

150 mm long 8 mm threaded rod

8 mm nut - 1 pc

8 mm parlock nut - 2 pc

8 mm washer - 2 pc

 

Notes

  1. Threded bar, nuts and washers, best in stainless steel, but zinc plated is acceptable;
  2. Because filament bobins may vary in size, you may need one or two spacers to fit;
  3. Two washers are advisable to avoid contact between reel and bearing
