Toy OTF Switchblade (Double Action)

This is a toy Automatic OTF Knife I designed. What makes this design different from a typical switchblade is that it not only ejects the blade when the switch is pushed forward but retracts when the switch is pushed backwards. This means it does not need to be manual reset like a classic switchblade. It also means its very fun to play with. Support Removal and Assembly InstructionsThe first step after printing is removing supports. There are supports on the handles, carriage, and blade. You can use the assemble animation and photos below as a reference of what it should look like after supports have been removed.A video showing how to assemble the design is located below.In addition to the 3D-printed parts this design requires additional hardware. It requires 3 screws, 2 springs, and 2 to 4 rubber bands. I have included the links to the exact parts required.Springs - https://www.mcmaster.com/catalog/129/1492/9657K614Screws - https://www.mcmaster.com/catalog/129/3372/90385A317Strong Rub
