Gravity Spoolholder streamlined nut

A remixed nut for the gravity spoolholder to fit closer to the spool to prevent binding and to fit wider spools and wider apertures. The original rubbed against the sides with one of my wider spools which prevented the spoolholder retracting properly so I designed this one to sit more flush with the spool sides. Partially threaded to reduce friction when turning on the screw in case of poorer print variations.

Remixed nut to fit closer to the spool to stop binding. Added X_large version for spools with wider apertures.
