About this 3D model

I've got a Panavise model 381. It is a smallish vise, but much bigger and heavier than a third-hand.I wanted to try to take advantage of this rotating vise head and make a simple modification to allow it to hold a printed circuit board for stability while soldering.PCBArmAndBase.stl contains a full set of parts. I thought that the depth of the pcb guide slot was too deep.PCBArmAndBase2.stl also contains a full set of parts. The pcb guide slots were squared off and an angle was applied to the base to give the arms a slight tilt in.
