Merry-go-round mousetrap

thingiverse

When the mouse turns the fence to get to the bait, the fence falls in a groove and locks in place. Not tested, my Makerbot is out-of-order for now. Have fun! Instructions Print the box, the fence and the top. Print some feet if you don't have anything to make a space between the box and the ground. Place a bait where the star is. Carefully place the fence so that when the mouse is almost at the bait, it falls and locks in place. There should be plenty of space between the interlocking pieces, so don't worry if your printer isn't fine tuned. (But it also means you might want to tape the top on the box, just to be sure.)
