TNT Plunger Clicker Fidget

Dynamite Fidget Clicker designed like an old fashioned TNT plunger, the type that Wile E Coyote always used in his attempts to catch the Roadrunner.

This uses a keyboard key for clicking.  I used: https://www.amazon.com/dp/B0FZJSKHF8

Set the key in the box and attach the lid/plunger and give it a few presses. It should ‘set’ on its own.  I have made dozens of these and this always works, however sometimes I do have to make sure the + in the plunger is a good fit.  I use the + from a broken keyboard key to make sure the hole is clear and fitting but you can do the same with a jewelers, eyeglass or any really small screwdriver.
