A miniature bottle opener to hang with your keys, always available in case of a little thirst!(quite fragile though, but it's cute).

3D Printing
Should be better printed with a reinforced material (PLA+, PETG, PLA Carbon...), but you can test with standard PLA it's quick to print.
Infill 100%

Inspiration
Design inspired by the PICO model from Pangea Designs which was launched on Kickstarter. The original model is made of titanium, so it's obviously more robust.
