I’m developing an inexpensive DIY Build your own slingshot kit. It’s composed of 5 layers of laser cut plywood. It comes with wooden pins so everything aligns correctly. You simply glue it up, then file the corners if you want, and/or paint it (if you want). The kits are expected to sell for $25 plus shipping. But quantity orders can be down in the $18 each for orders of 10 or more units. It will come with rubber bands and a custom leather ammo pouch. The problem is going to be writing directions for the darn thing. I’m contemplating just making a you-tube video for it’s construction.
