Catapult

This is my first designed thing. I hope you Enjoy.
ONLY THE FIRST FILE IS NEEDED TO COMPLETE A WORKING CATAPAULT the others are replacements, if a piece breaks or does not fit, and you do not want to reprint everything.

Set up instructions
1. align the holes
2. put the peg through all of the holes
3. Put the end cap on
4. Attach a rubber band to the to hook areas (one below the box on the end of the arm and the other at the center of the base.

Launch instructions.
1. Load up your projectile (beads, paper, plastic, E.T.C)
2. Pull arm back (farther back = more power)
3. Release to launch

IF END CAP DOES NOT FIT try printing it at 1.01-1.02 times the scale or 101%-102%
