Almost Stuart. Postage is more than the goods :( I may bulk up an order when I have time to plot and scheme what I may need in the future.

Spurry:
IF you have a bit of the polycarbonate sheet, I'm sure it will cut on a cnc router with a carbide bit. I think I've done 12mm polycarb in the past. Soon cut you one out if you've got some material.

PetG is easily available but apparently scratches easily

Andrew,

Many years ago a rep showed me a PetG sample and recommended that we could use it in preference to Acrylic or Clear PVC (for Clear PVC read clearish and bluish) for guards on electrical test gears. One really nice feature of PETG was that you could flame polish any scratches out of the surface. He demonstrated it by putting in a few nasty(ish) scratches onto a sample and then went over them with a cigarette lighter and the scratches all but disappeared. Unlike Acrylic it could also be welded with a hot-air gun and filler rod. I believe that we never used Acrylic again.

Phil.
