M3D Spool Adapter

50mm to 25mm Spool Adapter
=======================
This is an adapter to make M3d Pro Spools work better on the Hatch Box spool holder (or any spool holder with a ~25mm dowel). This moves the center of mass closer to the middle to reduce the force required to pull the filament into the printer.

I have included the archive Fusion 360 file incase you need to make changes. The parts shown here are the bodies named "Main Part" and "Nut".
