Thank you! I'm considering on making this out of Alu or Brass on CNC and was wondering if this was a standard thread or not. I can just measure the pitch and lead from the .stl, but I was mostly curious why you chose this form. If I keep this thread form I'm guessing that I'll need play with the tolerances a little bit to get a smooth fit in metal.

It is a custom designed thread which I developed to have smooth jerk properties when printed (parallel to the XY plane). The thinking was that this would produce the most accurate threadform possible and result in the best helicoid achievable with current printing tech. It seems to be mostly successful in that regard. I forget how many starts it has right now... 7? I haven't looked at the CAD in a year. Could get back in to it if there is something you need.

Nick, Another couple of questions for you, how did you decide on the type of thread? What is the thread form, lead, pitch and number of starts for this thread? tx

Thank you! I would love to see this evolve along the lines you mention in the docs. Another couple of questions for you, how did you decide on the type of thread? What is the thread form, lead, pitch and number of starts for this thread?

The STL is for printing. The .STEP and .SLDPRT are different versions of the original CAD data, in case you want to make any changes to the design. Don't be discouraged if the fit is tight at first... this is a tricky print to get right and requires a moderate amount of finishing after printing if the settings aren't dialed in perfectly for the print.

Hi, I'm pretty new to this stuff. Can you please explain the difference and need for the different file types? What is the .STEP for? What is the .SLDPRT for? What is the .SLT for?<br>Thank you so much for making this, it's awesome. I cannot wait to print it!<br>steve
