3mm Filament Clip

**3mm version** of the great 1.75mm Filament clip by [Walter](http://www.thingiverse.com/walter/about), designed to attach to the rim of a variety of spools (and as a result doesn't work on any of them particularly well). Depending on your setup, the clip may need to removed when printing to avoid snagging on the filament.

Should be printed in ABS or a similarly elastic filament (I don't think it will work well with PLA).
