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!
(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. 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!
UPDATE 24-10-2019: Made the trigger spring end a bit longer for more spring action.
30% for most parts, print the trigger solid!
PETG is too flexible I think so use PLA. Print the trigger SOLID!
Print it strong so it will not break while opening bottles.
How to assemble
One rubber elastic band (Post man type)
Bolds, Hex or Philips or what ever
2mm X 12mm neodymium magnet. Or smaler!
3 x M3 X 8
4 x M3 X 18
One coin: round 20mm and 2 mm thick. Such as a 10 euro cent or a 1 dollar cent.
Everything you need....
Start assambling this part but before you do insert the elastic band securing it with two tight knots.
How everything comes together....
Bold both halfs firmly to one piece and there you are. ALL DONE!
