Plywood panel linking joint for laser or router

thingiverse

A new joint concept for linking panels together which lie in the same plane. The squggly parts stretch ever so slightly like a spring to pull the panels together with a decent amount of force. As a bonus, it’s laser cutter friendly. This joint could make it easier to build up large objects off of a smaller machine or from pieces of scrap. This could also be suitable for something like a room divider panel, adult scale construction set, or maybe even a trampoline(!) Instructions The notches that recieve the squiggly "springs" are elongated to provide adequate force in 1/2" chinese birch plywood. If you want to use a thinner or more flexible material, you will need to make these notches longer. If you want to use a thicker or less flexible material, you will need to make these notches shorter. A good step for adjustment in plywood might be around 0.015". Again, work in progress :)
