We had mice show up in our house for the first time and my wife wasn't a fan of killing them.

I first saw this 140+ year old mousetrap design on YouTube and then a make someone had done as a 3D print on that other site. I came up with my own design.

I am not a fan of supports, so this doesn't use them. Requires two prints on the Prusa MK3/S.

My first iterations has issues with escape artists. After some tweaking, it works wonderfully as you can see with the little guy I caught! =)

Don't leave the mice in here for a prolonged period of time... they get stressed and may kill one another.

Print instructions

Nothing special about the print. The overhang on the door can be problematic if your printer doesn't span. Super easy fix is to hold a lighter up to it while its upside down and it will just lay flat.
