Friendly mousetrap, fully printable
by satoer, published
One of the fascinating things with 3D printers is the ability to print mechanical objects. To catch some mice, I've designed a mouse friendly mousetrap. The trap is fully printable and you don't need any screws or other hardware. Everything is press fit or screwable. Just add some peanut butter bread or other bait and you're good to go!
One thing I hated from existing mousetrap designs is the inability to easily add bait to the trap. So I made an easy sliding lock door with a hook for the bate.
It took my quite some time designing this thing. So if you print one yourself, please share a pic. I always like to see things I designed used by others and it encourages me to share more 3D designs.
Printed with 0,25mm layer height on a Felix 1.5 3D printer with 0,15 infill. Used 140 gram PLA.
Print every part, and press or screw together. See exploded view for assembly instructions.
Almost everything is printable without support material, only part mousetrap [Top-door] [V2].stl needs a tiny bit of support otherwise the hinges are floating.
The size is 20 x 70 x 71, if it doesn't fit on your print bed, try to fit it diagonally. Otherwise you can shrink the complete design. I've printed one at 80% size and it's fully functional, but I don't think you should go smaller. The bigger it is, the more comfortable the mouse will go in.
