Bottle opener simple

# Very simple no-metal bottle opener
I wanted to make a simple no-metal bottle opener and designed this based on memories of my favorite keychaing opener. That was made from soft aluminum, but this is 3d printed, so I needed it to be a little bit bigger. At roughly 10 cm from end to end it is still pretty small.

This is still a work in progress. I will try different materials because I suspect that the tooth that engages the edge of the cap to wear quickly.
