PCB Holder with Magnets

Update:

I added the single magnet design, that allows you to cluster around almost any board shape.

You'll need two of course.
I made it for .062 PCB material, but you can remix it and open the slots.

I have made other PCB holders for assembly and used guide pins. They work ok, but the guide pins limit the board size.
This one uses magnets so you can use a cheap piece of sheet steel and hold just about any PCB, until it flexes. The magnets also let you grasp the PCB board at odd angle
