1.75 mm filament figure 8 clip

This was inspired by intofocus's filament clip (https://www.thingiverse.com/thing:282242) which I wasn't able to make work for one n00b reason or another; the original's 1.75 mm diameter wouldn't fit my 1.75 mm filament, the little hook in the open end was too delicate to catch the filament, etc.

In the process of making a new hole I realized it really wouldn't be that big a deal to just make a figure 8 and run the clip around the spool once, rather than use a clip that might wear down anyway
