PCB holder alternative arm

I made one of pilotak's PCB holders and it has already proved to be very useful. The only thing I wasn't so happy with was the arm for holding components - I found it a bit flimsy and it tended to flop around. The pad part would also fall of the upper arm regularly - but that may be something to do with my printing technique!

Because of this I designed an alternative arm using OpenSCAD - it's very simple (and not as pretty) but it does have the same basic dimensions as the original. However, it is a lot thicker and therefore more rigid. I used an M4 nylon bolt, washer and 2 nuts to connect the two parts, but a metal bolt and nyloc nut would probably work just as well.

The pad will sit higher above the PCB in this design, so a thicker piece of foam will probably be required.
