I've created a Windows application (and now Mac as well) for creating custom thread files for Fusion. You can find out about it here. Hope you find it useful.
If you need to know how to offset threads for 3D printing then I've created a guide here which you might find useful.
If you would like to send me a tip for any help I've provided or for any of my software applications you've found useful, you can do this via my Ko-Fi page here.
