Makergear M2 Improved Spool Holder

Makergear M2 Spool Holder.

This thing holds (probably) any type of filament spool onto a Makergear M2. The default spool holder is too fat for some tiny little spools.

When you remove the default spool holder, save the little screws. these are needed (and will fit) for the upgraded spool holder.

The "end stop" screws on with a left-hand thread since otherwise the rotation of the roll might remove it while no one's looking.

Err... Correction!! I just updated the .stl files when I realised that in fact a RIGHT HAND thread is needed, not left hand :-)
