Edit: V2.1 expanded the opening for the screw head clearance
Edit: V2.0 I added a new stl with a cut out for the screw head. I have not printed it out or tested it yet
Edit: added a short version of the mounting arm to move the spool further back
A quick and dirty mesh mixer remix I made combining two models to make the ultimate side spool holder. Needs some polishing.
