This mousetrap can easily be printed, assembled and mounted on a bucket.
Put some peanut butter on the back wall of the trap. And use a plank or something similar for the mouse to be able to walk up to the trap.
Be aware that if your bucket isn't heigh enough (at least around 50 cm), you need to modify a lid so that they cannot jump out of the bucket. A little water also helps, but it might drown the mice.
The trap resets itself after a mouse falls through.
