3D model description

The Conibear trap is a design from the mid-1900’s names after its inventor, a Canadian trapper. The design is still favored by trappers for the low weight and size, versatility, and ease of use. I’m sure it would make a fun blacksmithing project, but I don’t have a forge, just a 3D printer. So, I designed a version using my favorite type of springs—binder clips. My design takes about 123 g, and is most similar in size to a 160 Conibear model, about 16” x 6” x 1.5” (406 x 152 x 38 mm) when set.

this one closes jaws on either side, lowering the loading on the jaw axles and eliminating the need for a base. It was designed as a model and doesn’t have the power of comparably sized commercial traps. But it does close pretty briskly. Note: it is not designed to snap shut without something between the jaws to absorb some energy. Try this and it might break.

However, the directions in which strength was needed required more additional hardware than I typically prefer to use. Two M4 bolts (12-16 mm) and nuts, some 3/16” (5 mm) wooden dowels, some epoxy/strong glue, and two 51x 25mm binder clips with 1” (25 mm) jaws will be needed. The binder clips I used can be found here. But fortunately, the handle length doesn’t really matter to this design so any a variation with jaws nearly an inch long will likely still work fine. A file for a longer (and thus more sensitive) trigger is included, as well as files for printable rods if you don’t want to use dowels.
Disclaimer: This is just a model, and neither intended nor designed for actually catching animals. Also, this style of trap may be regulated, depending on where you live.

I've designed a stronger version requiring less vitamins, too:

3D printing settings

• Material: Definitely PLA plus. Sintered steel would work too, I guess.
• Orientation: Place the white stripe level with the bed.
• Layer height: 0.2mm.
• Walls, Top/Bottom layers: At least 4 walls and 16 top/bottom layers.
• Supports: For the Adaptors
• Infill: 15% Gyroid for the adaptors, but use 100% for the Side Links (or use enough top/bottom layers to ensure they are solid)
• Total Material: 127 g
