Have you ever tried opening a soda can and just kept picking at the tab? You might break a nail! It's infuriating! Well, now you can pick that tab on the top of a can forever because this can does not open! Yeah, it's awesome. Side effects include possible insanity.

Printing tip: Print the tab separately. It prints way better. You can probably go lighter on the infill if you want to save some filament. Have Fun!
