Bottle opener

thingiverse

Insert a penny into place, and then use it as leverage to pry off your bottle cap. This gadget is extremely effective! Once you've successfully opened your bottle, you can position this over the top of it so that you can identify both your drink and where you put your bottle opener. You'll want to turn this onto its base – with the wide part facing downwards – before you start printing, since otherwise the structure might be distorted.
