Shooting Chronograph Adaptor

thingiverse

Adaptor for Nerf blasters without barrel attachment lugs, specifically designed for the E9800-X and its derivatives. Slip the aluminum barrel into the tapered end of the adaptor, working your way down to the stepped section until it fits snugly in place. The three 3D printed bolts used for centering on the blaster can be easily replaced with M8-1.25 hardware, but if you want to minimize scratches on painted barrels, stick with the printed ones. For a perfect fit, clean up the threads with a tap and die; I experienced shrinkage on my adaptor, resulting in a slightly tighter fit than expected.
