As you are not allowed to mix alcohol and flying this thing makes the mixture quite acceptable :-)
I used the airfoil profile NACA2412 (e.g. Cessna 172, 152, 120 ...) for the general shape and inserted the geometry needed to open a bottle of your favourite cold beer.
No more - no less.
Just place it like shown in the picture and go.
As I like the finish of 0.1mm resolution I just used that w/o probs.
If I'm somehow bored some day I will add some minor improvements which effect the optical appearance.
