Hi Fred, will do, i'm working up some designs right now. Glad to hear Tinkercad has a good reputation in your group. At first I thought it too simplistic, but now that I've gotten the hang of how it works, I enjoy using it very much. It's quite capable for a browser-based tool.

I am a coder type, so thanks for the tip about OpenSCAD, I'll keep that in my back pocket if I hit some snag in Tinker.

I'm surprised to hear there are maker types out there that would have fear of logic & math, but hey, to each their own! I'm sure they bring their own original insights a logical type like me would miss
