Friendly mousetrap, fully printable by satoer Jan 25, 2013

Featured Thing!

Description

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.

I made the PLA, works very well, I'm caught in the basement for nine moles. The first eight went smoothly, but the ninth made ??a hole in the side of the trap. The bait was small and the mole was there overnight, so it would become hungry.

Just caught my first mouse! This thing is awesome!

What I ended up doing was running that part of the trap through netfabb, and when I reprinted it, that piece was much sturdier! It's all assembled now.

Instructions

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.

I've having a problem with the little piece that the door blocker swings on. It keeps breaking off. It seems to be only the width of that space, even though the piece it's part of has carved out holes it looks like it should fit into. Any thoughts?

Didn't have problems myself. It's designed to snap-fit together. Did you print it smaler than the original size? Maybe put the part in boiling water to make it more flexable put it over the axis and bend it back in shape while it cooles down?

Anyone have the gcode file for the cage? Slic3r keeps crashing on me at about 60%, which I didn't realize until I had printed out half a cage and it just stopped. Annoying.

satoer on Jun 25, 2013 said:

I've sliced and printed also using Slic3r. I don't think my Gcode is very useful because its generated specifically for my Felix printer. Unless you've got the same printer of course. Isn't it a firmware problem on you're 3D printer that hangs on a specific part of G-code? Or is the Gcode only half generated? (Compare the Z height of the generated Gcode and the actual object)

I also had to do a little sanding. I think because PLA Is stiffer than ABS. The notches were a little too tight to press together. It's really a nice design, I didn't appreciate it until I had one in my hands.

Nice design, printed a couple already, time for my house friend to move on, next stop nearest field.

Printing this on medium resolution with the Makerbot 2 took quite some time (~~ 12 hours) and needed a little bit of filing/sanding before things came together properly. However, last night we caught our first mouse with it - worked great!

Thanks for sharing! I’ve already caught almost a dozen mice with it. And although they probably can chew trough the bars, they never do. They just give up.
I'm curious what needed sanding, for tolerance calculation for future models. I would love to see your print, can you share a picture?

Satoer, what software did you use to design this? and to make that screenshot with all the dimensions?

satoer on Jan 27, 2013 said:

I use 3D studio max for my designs. But It’s not the most convenient way for Industrial designing. I’m a motion graphic designer so that program suits me the most.
The exploded view I also created in 3D studio max and rendered it with V-ray. Everything you see I made myself, so sadly there’s no automated way the measurements, grid andarrows magically appear. But if you if you want to create arrows easily in a 3D program, use the “windings 3” font.

i like it, makes me wish I had a mouse

Nice :)

Ummm - it's "bait" not "bate".

satoer on Jan 25, 2013 said:

Thanks! I changed it. It'ts not my native language ;-)

It looks like it should work, but like CodeCreations said, it better be noisy when it goes off so you can go empty it. I don't think it much matters what kind of plastic it is, a mouse will chew its way out pretty quickly. It will probably take it a while to figure out it can chew it, after that I give it 1/2 hour, definitely not overnight. Maybe you could bait it with peanut butter mixed with benadryl. A sleeping mouse wont chew anything. :)

satoer on Feb 14, 2013 said:

Tonight I caught a mouse with it, and it probably was trapped all night. No signs of chewing on the PLA

satoer on Jan 25, 2013 said:

Well, the mouse in picture 3 was really caught with it. So it really works, but I havent tried a mouse endurance test with it

CodeCreations on Jan 25, 2013 said:

Wow, this is awesome! I wonder if the mouse would chew through it given enough time or if ABS is less tasty than PLA. I'm tempted to make a derivative for which you put the peanut butter on the print bed and then just print the trap over the mouse. :)

It's a beautiful design -- thanks for sharing it!

If you make that derivative, you're going to have to post a video.
