Trebuchet

thingiverse

This is a 3D Trebuchet - 225 x 160 x 122 mm. Capable of launching projectiles 6-8 feet. Only outside parts you need are the cloth and string for the sling and weights. I designed the basket for 4x1 oz car wheel weights. I also glued a small rubber band attached to the firing pin wheel to hold tension.
