companion cube "puzzle"
It's a companion cube to assemble.
It had a "bouchon" where you can put 2 little round battery, a LED and a little interuptor.
I have disigned it to be print in POLYJET, but you can try to made it with FDM process.

ps : i hav'nt disigned the cube, i have juste "cut" it in little parts to assemble
