This is an smart humane mouse trap. Fully printable and very simple to assemble. Just 3 parts are needed and the trap is ready to catch your little guests. I think it is just horrible killing those funny little mice. It is nicer to catch them up and let them live at any other place but your home.

I don't have any of them currently at home so I can't put the trap into action. I would be pleased if any of you can print it and give any feedback about it and let me know if it works.

It is very simple to use, put some cheese or any other bite inside de trap. When the mouse enters the trap it makes the front door turn and once inside it can't get out of the trap.

The good thing about this design is that the hinge you can see in the top cover is integrated in it so no assembly work is needed. I always try to design things as simple as possible avoiding complex assemblies which don't usually work when talking about domestic 3D printing.

2019/12/11 UPDATE I had the chance to give it a try and it works nice. It's probably not the most effective mice trap but I managed to catch one just 24 hours after noticing it was around. I post a picture as a proof ;)
