cap gun nerf dart tip

This is a nerf dart tip which is capable of holding a cap gun cap (with the help of some tape).Once the dart hits the piece of wood, target etc, the cap will detonate and produce a loud pop sound. Video on printables at RT.3d hereObviously it goes without saying, NEVER point this at a person or something you are not willing to destroy; this includes the fridge. I got my ring caps from here (others are available). Please tell me if ‘v2 for use without tape’ doesn't work and I will fix it.
