This 3D printed expanded battery door for the Nerf Stryfe is perfect for builds where you need the extra space for a larger battery, like a 2S or 3S LiPo. It provides an additional 9mm of space, which doesn't seem like a lot, but it is plenty to fit most of the popularly sized LiPo batteries used in the hobby. You can either reuse the screw on the stock battery door, or any of the popular Stryfe Thumbscrews sold elsewhere (Thumbscrew from Foamblast in last picture).

**Thumbscrew not included.
