I combined an F-22 model that I liked with the geometry from br3ttb's coin bottle opener to make the bottom of the F-22 a bottle opener. I considered putting the insert for the bottle opener where the weapons bay would be, but it wound up being better at the back of the plane. Overall it works out quite well because the F-22 model is quite chunky and durable.

I printed with about 6 perimeters and plenty of top and bottom layers to increase the overall bending strength of the model. I also used Cura's selective settings to make the bottle opener section print completely solid. This was probably overkill in the end, but it resulted in an incredibly stiff part.
