Breacher Destroyer Nerf Independent Three-Hole, Four-Hole Shells

The original shells don't have separate bore channels, so the air seal is a bit poor. That's why I designed these independent three-hole shells myself. There are two versions: one is fully printed with PETG and can be used directly; the other has a 2mm deep groove at the bottom, where an O-ring can be attached to further improve the air seal. I printed it with 95A TPU and attached it, but in actual use, it didn't significantly improve the air seal, so using the regular version is also fine. It can load 3 rounds of 72mm soft darts, or stack and load 6 rounds of 36mm soft darts. It's a lot of fun, and I hope everyone has a great time playing! ~~~
