This is loosely based on a desing from an instructable I found to create a paper catapult. "http://www.instructables.com/id/Launch-It:-The-Paper-Catapult." I\'ve modified the design some. Hopefully this will scale and print ok, I don\'t have any way to test it at the present.
Once it is printed you will only need a small wire or bar of some type to place through the holes to connect the arm to the body. Then just put some type of ammo in it and fire away. (its even \"green\", you fire it with your finger, no evil batteries required) My kids loved the paper version but they just weren\'t durable enough for them. With a couple of these, you should be able to have an all out battle. You should be able to use the small enclosed area to store your ammo when not in battle.
