Magnetic re-arming mouse trap (mousetrap)

thingiverse

This clever rearming mouse trap is engineered to capture multiple mice at once. It utilizes a compact magnet, which suddenly tips over when activated. To set it up, simply position the magnet at the thick end of the plank, smack dab in the middle. This clever design allows the magnet to serve as both a counterweight and a rearming mechanism. Next, screw a small anchor into place on top of the chassis, directly underneath the magnet. This will provide an added adhesive effect that helps keep everything secure. To calibrate the trap, slightly misalign the magnet and screw so that about 40 grams of weight - roughly equivalent to two AAA batteries - placed at the end of the plank will trigger a sudden tilt.
