This is a spool roller that replaces the bearing holders of "Universal Spool Holder".

Improvements:

• There is no need to adjust the bearing holders when replacing to a different sized spool.
• Rods can take more wight without bending.

Printed with PETG, 0.2mm, with build plate supports.

608 (8 x 22 x 7mm) skateboard / fidget spinner bearings are still needed as specified in the original Universal Spool Holder
