Helping Hands for Soldering

I'm too cheap and don't solder enough to buy a legit set of helping hands so this is my design. It's meant to clamp onto anything flat like a desk.

I needed to print supports for the 'joint' and 'clamp' pieces since they have round parts that I couldn't get to print smooth enough without added support.

I've included two types of joints, both work equally well. Reason for different parts is difficulty in printing. 'Joint' is a simplified version that prints easier whereas 'joint - old' is a nicer looking design but may not produce good results as easily.
