Update 4:

CAD; but I finally can make shapes!

In update 1, I started work on bringing the prototype to life, but honestly speaking, I couldn’t even make a shape. Thankfully, this CAD session was a bit better because I was able to make shapes and cut shapes into them!

The prototype is far from alive, but I was able to give it a shape. Hopefully I will be able to build on this design in future as I learn more and more about CAD.
