A hardy project for Fusion 360. I did get pretty far along in CAD.
Later though I realized non-parametric modeling would've made this project much much easier.
I Never expected to 3D print it as I didn't own one at the time. However, even owning one now, I feel it'd be a bit tedious to get all those moving parts to function just right. Even if all the fancy movements were handled by an Arduino :)
