Hoenir - Airsoft Ballistic Knife

cults3d

Hi Everyone, This project is pretty exciting, it's a ballistic knife, which means the blade shoots out of the handle. You will need a compression spring with a 10mm diameter when compressed and 30mm long, and around 70mm or slightly more when expanded. I used springs from an old Well bipod (there are two in each leg). Attach the spring to the bottom of the handle using a bit of epoxy or hot glue. You will also need a 25mm M3 screw. You can print the blade, using flexible filament if you want it to shoot safely at people, or print the blade mold with M3 screws to assemble the two parts and cast flexible resin inside for a safe flexible blade. I used this method to make about 20 blades with no problem. Like my projects? Follow me! License is non-commercial. Want to sell my stuff? Send me a message!
