Yet Another Go-Pro Goggle Mount

I wanted to find a way to attach my GoPro Session 4 to a snorkel mask. The mask is a weird shape, so I ended up cutting some cardboard to fit, scanning this in via flatbed scanner, touching it up in Gimp, converting it to DXF in Inkscape, and combining it with the other components in OpenSCAD. It snaps into place, so the bracket and camera can be removed easily.
