HOLIWISSSS EVERYONE!!!!!!!!!! I’ve finished version 2 of the arm (sorry for the terrible photo quality). As I mentioned, I completed an improved version; it now has greater reach so the claw can grab more things, and both the chassis and the arm are lighter—and, in my opinion, more stylish. I’ll be uploading the files soon so you can take a look or use the model yourself. I hope you like it!
