Switch plate for the Nerf Stryfe Automatic Fire Mod. This provides a flat surface which allows for a 21A microswitch or any other switch. Some cutting in the blaster shell and on the trigger is required for this install to work. Switch plates will have to be glued in place.

Any filament with standard settings on your 3d printer will work. I use PLA with 2 perimeters, 15-20% infill.
