Hi there, Has anyone modelled an accurate M12-0.5 internal thread? These threads are typically used for tiny CMOS camera lenses. I need to mount one of these lenses and would like to SLA a prototype, so I need a good thread (not sure it will resolve in SLA, but I'll try). Anybody have one pre-modeled (e.g., tooth shape, etc.) that they could send me or post? Thanks! Mike
