Optimized thread form for 3D printing featurscript

Is there a featurescript that produces rounded cross section threads that would be optimized for 3d printing? Something like a lightbulb thread? Thanks.

Not that I'm aware of, but I find that the standard 60° equilateral section ones print fine for me. Are you doing something unusual that needs round threads? It probably would be simple to modify the Thread Lab feature by @antlu65 for this if they aren't interested in adding round sections.

It’s a huge thread. Maybe something like 40 mm dia x 4 mm pitch. I’m designing a hobby project of a cylinder with two end caps that screw on and off. It will contain the 12 depth rods for my new to me depth micrometer. The only time I’ve tried to print threads on my printer were for small 10-32 threads a couple years ago, and that did not go well. Maybe I’ll try again at a large size as a sample. I just figured a thread similar to a lightbulb would be perfect for printing and common for designing for printing.

@nick_papageorge073 Here are the thread specs for an E26 bulb, which is apparently the "common" light bulb:
