XYZ da Vinci filament spool drill mount

I designed this spool/drill mount to let me quickly wind filament back onto the spools that go in the proprietary XYZ filament cartridges. This will fit the standard spools XYZ sells as well as my own spools which I designed to be compatible (http://www.thingiverse.com/thing:1705022). Using my standard household drill and this adapter, I'm able to refill my filament spools in a matter of minutes.
