Dual Plank Mouse Trap (magnetless)

thingiverse

This is a one-of-a-kind walk-the-plank style mouse trap that doesn't rely on magnets. Other than a coin or two for counterweight, it's completely printable, with no screws or magnets required. Typically, most plank traps need a magnet to release suddenly at the right moment and then reset themselves. However, this one uses leverage, friction, and a counterweight to achieve the same results, making it easier to make and still catching plenty of mice without needing manual resetting. The frame is designed to attach to a standard or tall bucket, cat-litter bucket, or rubbermaid-style kitchen trash bin. Most similar items should work as long as the rim isn't too thick, but I only had those three to test on. You may also need some tape to properly secure the trap so it doesn't move or fall off during use, depending on what you're attaching it to. I've been using this design for a live-trap (works for live or drown) by placing fluffy bedding in the bottom of a bucket, like shredded paper, which usually keeps mice from jumping high enough to get out. However, I did switch to a taller kitchen trash bin after a couple managed to leap out. During assembly, tape a quarter/coin to the Trigger Plank opposite the bait-grate end as seen in the image above. You might need two coins, so try adding a dime/penny to get the balance just right depending on how heavy the print is. If the trigger isn't sensitive enough, try sanding the tab on the back frame piece where the little point of the trigger plank contacts it or the point itself, but be careful not to overdo it. The counterweight also affects how sensitive the Trigger mechanism is as well as how level the top plank sits. Other tweaks may also be necessary depending on how it prints for you. Please feel free to make suggestions if you think of a way to improve this design or if there's something I need to fix.
