Spool, fully parameterized

This spool model is fully parametrized (Fusion 360 file enclosed).

The spool will print without any support structure, see paragraph "design"

The hexagon hole facilitates winding up filament/wire/yarn:


Take a threaded rod
fasten it in an electric screwdriver
screw two nuts on the treaded rod close to the screwdriver
tighten them against each other
push the spool over the first nut
secure spool with another (winged) nut
start winding with the electric screwdriver
