COMPOSABLE INSERTS FOR DIY TRAPS
A snap-together spike funnel that converts a storage tote into a trap.
A threaded flange is inserted through a hole cut in a container such as a storage tote and secured from inside with a lock nut. Individual thorny spike elements snap into slots around the flange, forming a cone-shaped array pointing inward. The mouse pushes through the converging spikes to enter; the spikes flex inward to admit it and then bar its exit. The same components may be assembled at a larger scale, and the finished trap may be floated with foam or weighted to sink for use on fish.
“For aquatic use, the resulting trap can be made buoyant with foam or weighted to sink.”— Nick Suteerawanit, from the specification
And the world did not beat a path to his door.
