For some added MEGA explosive fun during your next Nerf War, I've made a 3D printable replacement tip for foam MEGA darts that holds "party snaps" that explode on impact!
The tips are printed in three pieces: the tip, the screw mount, and the head that holds the "party snaps". All three pieces are supplied as individual STLs, so you only need to print what you need for replacement components. I've tested the darts up to 35 feet away from a smooth surface (garage door) and they still explode on impact. I haven't had a single jam as the tip fits perfectly with the foam dart.
There are STLs for both the solid head as well as the head with holes. I highly recommend only printing the aerated head as they are much louder and fall at impact instead of bouncing back 6-12 feet.
Print time @ 0.2mm: 20 minutes per set
