I feel like this might/should exist, but I can’t find it. Is there a program that allows for replacement screw cap generation by simply entering a diameter, depth, thread gap, and thread pitch? Would be really nice to have something like that. I the meantime, maybe I’ll consider printing tpu corks/ stoppers with mid diameter equal to vessel opening diameter.
You can do some basic thread generation in tinkercad the thread generator has some options.
