Spool Holder 54mm

Spool Holder for spool with inner diameter of 54 mm.

Print 2 "nuts" and 2 "wheels" per spool (left parts and rights parts are the same).
Use a bolt and a nut to maintain parts in place (see specs below).
No bearing required.

"V shape" of the nut is used to make the spool roll on his support with very low amount of friction. Considering the quite low diameter of the smallest diameter of this shape (approximatively 19.4 mm), it roll quite good on my custom support with a corresponding "V shape". I will provide corresponding support - an inverted hanger - soon: I need to improve its design ... ;)

No tools are required to assemble or disassemble this spool holder : just **kindly** tight it by hand on the spool.

Picture of the orange spool holder show my previous design that was fully round.

Parts needed (per spool):
1 x Bolt 5/16" x 3 1/4"
1 x Nut 5/16"
