I measured this at 12 TPI. Measured both the inside and outside diameter for thread peaks. Then looked up on line the thread depth for 12 TPI. Didn't quite match the dimensions of the parts so I went with slightly less.
It threads on beautifully from one side. Won't on the other. Not sure why other than that it was the plate side and perhaps some distortion on the initial layers.
The plan is to now extend the drawing into a lens and print it with clear filament.
