easy to print and set up live catch mouse trap, simple put screws through as the little prison bars and click the lid on, throw some bait in and youre away 

slide the doors and the mechanism in place, may be a little tight depending on printer tolerences so id recommend light sanding if needed. 

peanut butter or seeds inside (note the holes i melted to put peanut butter in, far faster to melt or drill holes than print them) 

the mouse will go in and stand on the mechanism which will close the door behind it (not foolproof if their tail is still poking out loads) then they only have 1 option to go through the next flap which closed behind them.

lid is push fit so easy to remove.
