Dual 3mm Filament Clip

Because there aren't enough filament clip designs on Thingiverse yet.

This clip works well with the wide variation of "3mm" filaments, which seem
to range anywhere from 2.70-3.10mm. It works with any spool design since
it doesn't clip to the spool, and doesn't extend beyond the spool perimeter.

Designed from scratch using Sketchup, but the "spring" portion was inspired
by the design in thing #593804. The Sketchup file is included in the downloads.

I like to print these in Ny
