Nerf Swarmfire Trigger Switch Plate

The default version of this file should accommodate for most microswitches similar to the model in the photos. You can shorten your level arm length, but in my case, the full length clears the shell wall without any issues.

If you chose the [no holes] stl, a 7/64th drill bit should match MOST mounting screw hole diameters, but I'd still double check by fitting the correct drill bit to the diameter of the mounting holes for your specific model of switch.

Instructions (see photos)
1. Shave down the top support for the stock switch retention slot (first photo)
2. Decide if your microswitch switch mounting is similar to the pre-aligned stl
3. Glue the plate so the side furthest from the mounting holes is flush with the 90 degree angle created by your shell reduction
4. Attach your switch so that its lever arms intercepts the path of the stock trigger actuation path.

Note: I use Cura for slicing, but in any case, rotate the model so it's flush with the print bed.
