Ballista

Catapults are over-rated! Print out this ballista and annoy your friends as you shoot tiny objects at them!

The max size for a projectile is 1 inch in diameter.

Slide the track into the stand, put the screw in the hole, load the projectile, put rubber band around the pegs and projectile, and finally pop out the screw to fire!

(Some Assembly Required) (I am not responsible for any injuries that may happen directly because of the ballista or when your friend hits you after you have pelted him with marbles for the 48th time.)
