    Found it!
    I don't want to add this to my YT channel yet, so here's a dropbox link. I may remove it later, but you can download it by right clicking and selecting "save as" or something. . .

    None of my rubber bands work, and I don't want to buy any. So for now, I'm not going to sue this grenade...

    It sticks out a little depending on the tension of the rubber bands. Perhaps try a tighter one to old the white rods, or a looser one underneath?

     Keep practicing! It should take no more than 5 minutes to build/ rebuild. Also, try my Fragmentation grenade, it's easier to build/rebuild.
    BTW, the whole grenade should not fall apart, only the 4 gray and 4 white rods should.
