These are Space Invaders plugs/spacers for people with stretched lobes. I modified sideburn's existing invaders to be thinner and smaller, then glued them to plugs that I made in OpenSCAD.
Generate some plugs using http://www.thingiverse.com/thing:16134
Print out two plugs and two Space Invaders
Use a solvent or super glue to stick a plug and an Space Invader together
- Wear 'em!
