Mouse Trap-Door

This is used with a cheap plastic shoe box. It requires a 2 7/8 x 7 5/8 inch hole in the lid. Glue is used to adhere the frame to the box lid, as well as the tunnel section to the frame. I use Dap Rapid Fuse along with a Shoo Goo type of glue.Supports are use for the frame only. 3 US Quarters are used as counterweight. I glued them into the hole on the bottom of the lid.
