Nerf Elite Trip Mine Booby Trap

thingiverse

This is a step-by-step guide for building a DIY Nerf gun, specifically a Nerf "mine." The instructions cover post-printing finishing tasks, deployment, and operation. The steps include: 1. Printing the mine body. 2. Finishing the body by sanding inside the cylinders, cleaning up small holes in the tabs, and sanding or painting the exterior (if desired). 3. Printing the pusher mechanism and trigger mechanism. 4. Touch-sanding the pusher mechanism to improve smoothness. 5. Attaching the trigger mechanism to the body with a nail. 6. Inserting the pusher mechanism into the body. 7. Attaching rubber bands to retain the pusher mechanism. 8. Optionally, predrilling a hole for an eye hook or screw eye to keep the trip wire direction correct. The deployment and operation steps involve: 1. Stretching the rubber bands by pulling the pusher mechanism apart from the body. 2. Rotating the trigger mechanism so that the small arm points down and the long arm points outward. 3. Installing a metal rod in the detents of the pusher mechanism and trigger mechanism. 4. Installing Nerf Elite darts in the dart cylinders. 5. Testing the device by pushing the long arm of the trigger forward toward the top of the body. The author also mentions that they revised the trigger mechanism to include a lever that trips the mine with a variable and consistently repeatable trigger pull weight, eliminating the need for sharp or dangerous edges. The body shape was changed to a hexagonal design, and the rubber band retaining slots were modified to accommodate multiple 1/4-inch rubber bands.
