Simple Spool Holder for Spools up to 3kg
A perfect temporary solution: no bearings required, no moving parts, and easy to print. For smoother rotation of heavy spools, we recommend wrapping the holder with fabric. Note: the holder may need occasional adjustments.

Spool Holder Assembly
To assemble the spool holder, place the spool between the two main parts and connect them. Then attach the bottom part and use the 4 guides to secure the entire structure. Quick and easy!

The model can be printed on the A1 Mini.
