Mike's Spool Holder

I was really liking the roller type spool holders, but once the filament got low it would fall off.

This is my new favorite spool holder.

I printed in ABS at 50% fill (you might want to go higher), then glued it together with acetone. Screw holes are included.

It uses two bearings: http://www.amazon.com/gp/product/B002BBGTK6

1.stl is the only part that needs supports. Attach the bearings with two M8 bolts.
