Yet Another Mask Clip

Yet another clip to tie a mask elastic together without putting strain on the ears.
This one is just the right size for the masks I have access to.

Designed in OpenSCAD, so in theory you can change sizes like width, height, thickness, and overhand to trap the elastic bands.
I haven't tried other sizes once I added holes to reduce filament use. So double check they are lined up correctly if you try other sizes.
