4-40 screw for cutting a thread

I’ve provided the STL because I was forced to in order to publish this - but the intention behind this is to insert it into your 3D model and subtract it from the model, in order to cut a threaded screw shaft. You shouldn’t use the full length of it, it would have too much resistance against the screw. Generally what I do with this is put the end of it in the bottom part of small project box enclosures and subtract it. I don’t know why I made it so long, you can chop it up if you’d prefer.
