Description
The intent is to be an open ended construction toy to let my kids build and experiment with various types of catapults. The design is very similar to TinkerToys. This small size allows the entire set to fit inside a small bag.
Parts are all easy to print, no supports or post processing necessary! Print the TPU parts with like 8 perimeters (basically completely solid) for stiffness.
