This bottle opener will be the most important fridge magnet you will ever own!

Requires a magnet with a diameter of 12mm and 3mm height. 

This design is leaned on a popular thingiverse design (see: https://www.thingiverse.com/thing:775265), that had no magnet. So I designed my own, grabbing some vertices and perfecting the shape.

Print advise:

• Allow 5 perimeters.
• Print lying on the side in Y direction to allow the cooling support the steep progress at the handle. (The STL should be already oriented that way.)
• No supports needed.

You can also have a look at the blender file and make your own changes.

Update 2022-08-26: I added all options for the holes as a direct download.
