Darth Vader voice changer 2.0 part 4: almost finished

This is the fourth of a series of five where I design and build a Darth Vader chest box with the HT8950A chip. The series involves all the instructions for the electronics, laser cutting and a bit of 3d printing.

Designing parts for the Darth Vader chest box with OpenSCAD

I started using OpenSCAD for my Darth Vader chest box. OpenSCAD is a lightweight 3DCAD program that’s free and open source. It’s uses a scripting language to define the desired 3D model.
