Catapult rubber band powered

For this catapult you need 2 rubber bands, 4 screws, ideally 3.5 mm, and metal rod (diameter: 3.5 - 4 mm, length: 9 cm)

I had a wierd screws so I modeled similar sized hole and jammed it in. 

If you have standard 3.5 mm screws. You can use model “Catapult part_2 3.5 mm”.
