I admit, this was a bit of a silly project… but at least it works!

Basically i designed a gun that uses the spring in a mousetrap to fire a bullet with a decent amount of power.

the mousetrap I used has the following dimensions:

LxWxH = 96mm x 48mm x 6.5mm (this is just the wooden base)

If you want to print the gun but your mousetrap is different, than I would scale up or scale down the model so your trap fits as well.

I have included a small “test_part” that you can scale up or down and to test if the trap fits… You should then use this scale for the other parts as well

if your trap is a lot bigger then mine than you should probably not try it, or find a different trap :-/

how to assemble:

1 insert mousetrap from the side

2 place slider

3 add spring and aiming part

4 add trigger

5 add 2 levers in front

6 put long pin through levers
