Summary

This battery door is meant to cover a lipo pack after you modify your Nerf Rival Perses to accept lipo batteries. I designed this one to be easy to attach; other designs force you to route wiring through part of the door and I found this to be finicky.

To install the battery with this door: connect the lipo pack, place it in the battery tray in the blaster, giving the wires a nice curl if they're too long. Lock the top lip of this tray into place, and rotate it down to attach the bottom piece, gently sliding the battery up a few mm if necessary. The stock battery button will lock the door in place.

Print in the orientation shown in the photo (skinny side to bed), brim recommended but not required if you have good bed adhesion
