Humane Mouse Trap

This is an adaptation of Thingiverse user mikejeffs mousetrap. My mice seemed to be pretty tricky and pulled the original latch off from the inside and escaped. I went through a few iterations and eventually desired to have a simple falling latch. Use some super glue to attach a nickel to the pocket in the latch door. I also included the other pivoting latch that didn't work well for me, but might for you. The deadfall latch has the nickel facing inward and the counterweight latch has the nickel facing outward. The top of the deadfall latch can also accept a 1/4"-20 screw and nut to ensure the mouse can't pull the latch inside and release it.

I also modified the back of the trap making a removable door because I had a hard time getting the mouse out the trap door side. (He's fine.) The end cap should fit in with friction alone, but to be safe you can also lock it from the top with a paper clip. I designed it to use bamboo skewers to fit in the inside holes loaded with peanut butter
