      Ok I’ve managed a male and female thread on a 150mm diameter, with a 0.3 offset, . It’s very tight can wind it on for 2 threads , and that’s it. Tomorrow doing another female with an extra 0.3 clearance on all faces, so see how that goes. I think it’s the shrinkage on the printer that’s causing the problem
      Thanks Guys for all your help

        That's probably it. You'll have to work that out based on the material.

                  Hi guys
                  Again thanks for all your help
                  Is there a chart you use to look up thread dimensions, pitch, tpi , crest etc
                  I was trying a m22 x 2.5 and got a bit confused on the chart I was following, so I asked ChatGPT
                  After 4 hours of me telling it, it was wrong, it finally agreed 🙄
                  I was drawing it in SU then asking it questions on the iPad
                  When I get home I’ll upload my figures and see what you think, the thread looks good on the screen, but that doesn’t mean it will fit
                  Thanks Dean

                        I would use the following site:

                        Link Preview Image
                        External Metric ISO Thread Table Chart Sizes M20 - M55

                        Metric external thread size table chart for sizes M20 to M55 Bolts and screws per. ANSI/ASME B1.13M-1995.

                        favicon

                        (www.engineersedge.com)

                        I wouldn't bother with the radiused corners because they'd be too small.
