Multi-Diameter Filament Spool Drill Rewinder 1/4-20 Bolt - one piece remix

This is a remix of a remix of a conical self-centering center hub mount for fillament spools to mount to a drill with a 1/4"-20 bolt and nut. I remixed the original 2-part model to combine the hub and cone into one piece with a chamfered internal hex bore so it could print in one piece to better suit my needs. On the original, the parts off my printer didn't fit together well, so this is a good workaround for that issue, and faster to print.

I used a 6mm nozzle to print in ABS with 5 walls and 5 top/bottom layers, 10% gyroid infill in ABS. The original suggested using 8 walls at .2mm layers on the center hub and 15% infill.
