Nerf Gun

thingiverse

My OP nerf gun design, this beast can reach RPSs of 15 and fire so hard it'll leave marks and disintegrate the dart upon impact. I used two 540 dc motors for shooting, (the higher rpm you can find the better), and two 400 rpm 6v N20 motors for pushing the darts. (I'd recommend 12v N20s in the 400-500 rpm range but these are all I had). I used a 11.1v high power li-ion battery and regulated the voltage at 10-12 v (depending on what RPS I want) for the pushing motors using voltage boost module. I used mechanical 3v relays to drive the shooting motors. The switches in the handle are DPDT 6 Pin 1 Position momentary switches that I extracted from an old store bought electric nerf gun. I used a variety of assorted M2 and M3 nuts and bolts ranging from 6mm to 26mm in length for construction. I kinda cheated and used glue to attach the decorative shell pieces. I used 6x3 neodymium magnets in the sliding cover to lock into place. I extracted some random springs from pens and used 3mm metal rods to make the firing trigger. The holes in the lower shell are so that adjustment knobs on any potential voltage regulators that you choose to use can be accessed with a screwdriver.
