I frequently build parts, both aluminum and 3d printed, which are used with thor components. Using Fusion360 from Autodesk, it’s simple to add threads into a hole, or even create pre-threaded holes in objects. Luckily, Fusion360 even includes a C-Mount thread option.
But – the SM1 thread from Thor is another matter. I had to add one to a part, so I found this nifty trick in fusion which supports adding custom threads to your install.
It turns out Thor provides the required information to form the threads, so using this page I was able to pull in the thread settings, and generate my own thread selection.
For anyone who just wants to use the threads in their copy of fusion, please find the file located on my Github page here.
