This is a remix of the great toy bear trap, TRAP! by IdeaBeansNZ. There were a few improvements that could be made to it, however, and a couple of people made them: improved springs that are stronger and require no support by MacGuyver and the jaw fix that allows both jaws to stay flat when the trap is set by sthone. I've included all of these improvements, plus a couple of others that I made myself:

Improved (v3) jaws that close up easily when the trap is tripped. Tapered teeth allow the jaws to close all the way without binding.
Improved (v2) clips that hold onto the shackles (u-bolts) much better. They tended to pop off when the trap was tripped.

I used Tough PLA for all of the parts. The springs seem to work well enough with this material. Time will tell if they will last. I'll have the kids do a durability test on it. The only glue required is to attach the trigger pad to its lever. A drill bit may be needed to clean up some of the pivot holes.
