Ball Bearing Fillament Spool Holder

Modification of Nielserik spool holder-low friktion https://www.thingiverse.com/thing:1426106
(I have included the 3 parts from the original that I didn't change.)

New mounting parts to allow mounting on the back of a flash forge creator pro.

The original seems to use No. 2 screws for assembly, but with a wall thickness of 3 these can be drilled out for a M3 screw.

Also for attachment of the clip piece I used m3 x 16 mm screws. Ball bearings are 6mm airsoft bbs.
