Tension to Compression Spring Inverter

cults3d

This is a fun print that converts a tension spring or rubber band into something that applies force when compressed, utilizing its natural tension. This design works with springs, rubber bands, or any other flexible material you can fit into the hooks. It's not entirely clear if there's a practical use for this print, but I think it's a cool concept that's quick and easy to print. Printing and Construction Print the legs as you normally would, with the long side on the bed. Print the hook connector part standing up at 100% infill with minimal supports, just like shown in the pictures. For assembly, you'll need super glue or some adhesive. Each hook connector slides onto one leg and is glued onto the other. First, slide the hook connectors through the legs so that the hooks face away from the feet. Then press fit the connectors into the rectangular hole at the top of each leg. If it all fits together smoothly, remove the hook connectors from the slots, apply a small amount of super glue to them, and press the connectors back into the rectangular holes again. Let it dry completely before testing it out. I used PETG, which bends slightly with a strong spring, but I think PLA would work best because it's more rigid. Do not glue the hook connectors into the legs until after you've slid the hook connectors onto the legs. You won't be able to assemble it if you do so.
