Threaded spool for Wire Spool Holder

This is the spool that goes with the Spool Holder.

I didn't like having the edge of the spool glued or friction fitted in the original model. I redesigned the spool with threads now you just screw the parts together and it stays firmly in place.

The tolerances have been adjusted and the spool/pins should fit together without too much pain.

You can use a coin or a screwdriver for the pins, but be careful it's still small plastic parts and can break.
