companion cube "puzzle"

thingiverse

It's a companion cube to put together. This box had a spot called "bouchon" where you could place 2 small round batteries, an LED, and a little on/off interruptor. I made it so it can be printed using POLYJET technology, but you might also want to try printing it with FDM machines. GL Update: I didn't create this cube, I simply split it into pieces that are easy to assemble. Instructions Print all 8 coin parts, 12 stopper parts, 6 small heart parts, and a single body part. Also print a "bouchon" cover piece. Go out and buy some batteries - there are two round ones needed. Get a tiny on/off switch too. Grab an LED light as well. Put everything inside the box you made from those little parts and then hook them up with cables, lights, and buttons. Enjoy!
