Halo NERF Bullet

I bought myself a cheap "Nerf" gun at the thrift store, but it turned out to be an old Halo-branded one from a different company, with a non-standard bullet size. Worried about having only six matching bullets, and the high prices of replacements, I decided to try printing some, with quite a bit of success! I was afraid that the solid tip would be too painful, but the rough surface along the sides decreases velocity enough that it was actually less painful. It's too bad that it slows it down, but it's still very usable.
