So, I decided to try out OnShape as a CAD software. Previously I'd worked primarily in CREO 2.0 and struggled with it (I know Solidworks and Inventor far better). I'm also a Mac user and using a VM to do CAD was annoying. So I heard about OnShape and decided to see if I could whip out a frame in it. Guess I can.
You can also copy the file and make modifications inside OnShape at (I assume) Mini Robot Frame
