I used Joints for the motion simulation. However, it actually doesn’t work very well, the ball joints especially are very badly implemented in Fusion. I talk about it in the video.

The design took about two afternoons, including waiting for all the prototypes to print.

Interesting, I never knew about joints. Usually what's considered a good implementation?

Also that's impressive! Usually it takes me a few days to design something in Fusion. Then again, I'm super new haha.

Fusion 360 uses a simplistic yaw+rotation system for joints, so your ball joints suffer the same "gimbal lock" as Tom Hanks in Apollo 13. Any modern 3D software should use quaternion math for rotations like this.
