It was very kind of you to reply considering you are building a house. Exciting I know, I have done it myself. We'll call it a total rebuild on pre-existing foundation..:-)
. I deleted my comment because I appeared so lacking of insight, and curiosity, the prerequisite availing oneself of all resources.
Of course I did exactly as you suggested, Very nice introduction to OpenSCAD
I have a new box underway for a DIY power supply and Hakko soldering PCB with STC controller and firmware. Gosh knows I have been trying for some time now......Excellent
There will be a little something in your Christmas stocking
