Twist-Off Bottle Opener

This is an opener for 21-tooth 1 1/4" twist-off bottlecaps (those found on most bottles with twist-off caps). It includes a hole for a 30mmx17mm (1.18"x0.669") magnet with a 2mm gap between the magnet and the back of the opener.

(place the magnet inside the hole, with a bit of double-stick tape to hold it - if the magnet's strong enough it should be able to stick to a fridge)

NOTE: You may have to rotate the object 180 degrees around the X axis in order to print it on the large flat side.
