simple arm

Parts for a basic robot arm. In the pictures, I used https://www.thingiverse.com/thing:3436276 as the claw. Hole in the bottom of the base is for pennies, to weigh the arm down so it doesn't tip while lifting things up. I just put a piece of tape over the hole to keep the coins in.

Not all parts in this thing are needed to make the arm in the pictures. I just had some extra experimental parts that I made for other applications.
