Torsion Spring Catapult with Adjustable Force

A catapult I've designed with large torsion springs that have an adjustable tension position. The latch is automatic. All gold colored pieces are from PETG and the rest from PLA. 

Modeled in SolidWorks, two versions of the side are provided. One is a simple solid body and the other is split between the decorative black pieces and the brown piece with the wood texture applied. No fasteners required, drawn with 0.2mm per side clearance on moving pieces and 0.1mm per side clearance on press-fit items.
