I was going through the free class on youtube and after a couple, I made this, Stupid Robot.
And then after learning beveling, though I still had problems, stupid Robot v2.
Difference between it and just the primitives exercise is that I used mirroring and Shift D.. and rotation.
But I still think it counts.. Doesn't it? :D
