It is a holder for Out In Nano, it all fits, and has holes for 2x3 magnets. My printer wasn't big enough so I had to render it. You should probably split bases so you can print them separately. I recommend printing the bolt type things with the bigger parts, because the bolts are so small, it will help the bolt layers cool in between layers.

I really hope I win so I can use the portable espresso maker, and a P1S would really help me out. Please download my model.
