Backyard Catapult with PVC pipes

This backyard catapult can be printed on any size machine and uses PVC pipes to add strength and speed. If you're in a real hurry, use PVC elbows and only print the swing arm parts and T connectors. 

See my Youtube for pointers on assembly.

You will need 1 inch PVC pipes:
Six 15 inch pipes
Two 30 inch pipes
one 27 inch pipe (throwing arm)

Print 6 corners and 4 t's

These pieces fit a bit loose on my printer – we had to glue them in place. Please test one first to see if you want to size it down to 99% for a tighter fit.

Swing arm MUST BE LOOSE fit.
