Joining in on the mouse trap craze is the Flaptrap.

The theory is simple. Door opens from one way.

The trap comes in three parts.
The Door which slides into the body and tightly clips on to a solid hinge.
It will open when small pressure is up on it but is blocked from opening on the opposite side.
The body houses the animal obviously. It includes a built in clip as seen in the pictures. This inserts into end of the unit with liners on each side to allow for smooth placement and more security of the animal. Simply press down on the the clip to remove the end from the body and release the trap without harm to creature. The flaptraps end piece also includes a small baiting shelf to make sure the animal reaches the end allowing the door to close.

Unit is certainly makerbotable. Though I have not tried it yet.


Print it.

Clip it together.

I'm thinking you might want to add a bunch of bores all around the sides so the trapped rodent can freely breath fresh air maybe ... or at least be more comfortable while it awaits relocation or a long slow death because somebody forgot to check the traps ...

Also, having air holes will allow a person to more easily see inside the trap without disturbing the trap.

Sounds good! Ill fix that up today! The reason I lowered the complexity of the body as i didn't want to slow down the build process with every stop start that the holes will introduce. But its might not be avoidable.


The whole idea about a printed rodent trap is ju brilliant. Oh just that thing about mice don't mind eating polymers. But never mind me i just go over here and print some jars to keep my annoying marks in
