Guaranteed hilarious fun in any situation when you brought this with you as a gift or just for the fun of it.

(Scroll down this page for the assembly instruction!)
Just a set of M3 bolts, an elastic rubber band and you'r all set. Oh I forgot, a 10 cent euro coin or, 1 dollar cent, or equivalent. A 12x2mm neodymium magnet completes it. Available here for a few cents:

This is a strong and wel build design. It's also safe as a bottle cap is a very big object and the speed it's fired is gentle. And you will never aim at a person wil you?
The print does need some support but only for the two body halfs. No further cleanup.
Have Fun and please give me likes please and of course share your make!
MAJOR UPDATE
First model is designed for 26mm caps. I have now designed an experimental version according the international standard for caps, DIN-norm 6099. Cap size 32.10... Still experimental until I got the feed back from you, the community, that it shoots well. Only the barrel inside is resized. All others measures and parts are unchanged.
UPDATE 24-10-2019: Made the trigger spring end a bit longer for more spring action.https://youtu.be/32VpDq0FvxE
UPDATE 15-12-2019: Enhanced clearances (0.5) for the trigger axle and pusher components for both models after feedback from the community. Advice to tune your slicer. +/- 0.2 should be your maximum tolerance.
UPDATE 28-12-201: STEEL AXLE Some of you complained about breaking the plastic axle. I changed the position of one of the construction bolds so it is an axle to. As for me not the most elegant solution because if your 3D setup is tuned well it should work fine with the plastic. Both models are here to download.. Pick wise...
