I’m working on a 3D design that involves a screw-based connection between two parts and I was struggling to dial it in with BOSL2’s threading library. After some further reading of the documentation, it turns out that what I needed was the bottle caps set of methods and functions. My first test has created a pair of parts that mesh together well so I can proceed with designing the components I have in mind and joining them with a reliable “bottle cap” connection.
