Improved Conibear Trap

I’ve made several improvements to my design for a Conibear trap. These are listed below:
• The jaw design is stronger. Using four pieces allows the strongest direction of the material to be used to full advantage. Each jaw is approximately square, with 6” (152 mm) sides.
• The Spring Adaptor pieces have been made wider, allowing one to use two binder clips on each side for additional power, which is recommended.
• The trigger mechanism no longer interferes with the jaws completely closing, and is equally sensitive to disturbances from either side.

• The only non-printed parts required are the binder clips.

These changes raise the material demand to 326g, but the extra material cost is offset by not needing any non-printed hardware besides the binder clips. The previous version was a model…but this design is large and strong enough to catch small pests, such as squirrels (which is the creature I successfully tested the design on). But the increased forces and power bring greater risk for injury. Exercise care when setting and using. Don’t say I didn’t warn you. This is not meant for entertainment purposes.

You’ll need pliers, a soldering iron to weld a few pieces together, and 2-4 1” binder clips. 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 and handles about 0.075” in diameter will likely still work fine.
