I'm doing some mucking about with threads in #freecad. I had steeled myself for some hardcore learning, installation of plugins and whatnot.
Nope, just a few clicks to make a rough copy of this weird unthread for a bung on our sailboat. Good stuff. I have a few versions printing now to see which one fits best.
And no, the printed bung won't be used below the waterline. It's for securing a hatch lid.
