Summary

Space invader keyrings - I adapted the original sprite outlines and added a mount point for a keyring.
Designed in FreeCAD, source files included for adaptation and remixing.

UPDATED: The hole at the top kept breaking, so I've redesigned a little and widened it. Also made the key ring thinner (now 2.5mm) - suggest printing at 0.3mm resolution and 100% infill.
