This upgrade part is designed to enhance your mousetraps, making it more likely that the mouse will trigger the trap while going after the bait. Very effective when you have tiny, ninja mice who take the bait without triggering the trap.

I recommend the Square Beta cage, as it prints better and is harder for the mouse to get past.

Simply fill the printed cage with cheese, attractant, ham, or whatever your pests will eat. Then slide the cage onto the lever of your mousetrap (where you would normally put the cheese), and set the trap as normal.

This upgrade works by making the mouse poke its nose between the bars of the cage, applying some force to the lever, triggering it.

(the design opening is to fit 10 mm wide x 1mm thick mousetrap levers)

Note: I will not be held responsible if by using this upgrade you accidentally kill off all the less ninja-like mice, leaving only a rapidly evolving race of super mice. You have been warned.
