Now This is FUN!
Guaranteed hilarious fun in any situation when you brought this with you as a gift or just for the fun of it.
And very easy to make...!
Just a set of M3 bolts, M3x15 + M3x8. An elastic rubber band and you'r all set. Oh I forgot, a 10 cent euro coin or, 1 dollar cent, or equivalent. And if you go really PRO add in an 2mm neodymium magnet.
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! https://youtu.be/32VpDq0FvxE
