M6 thread nut screw

A M6 screw thread designed to fit off the shelve M6 screws.
Has been tested to fit pretty well.

Use the thread.step file to make your own nut or screw. Simply union to an inner core for a screw or subtract from a outer hollow shape for a nut.

Note: maybe scale the thread by a few percent for the screw and enlarge the threads by a few percent for the nut -- to add some margin.

The thread 108 means it is scaled to 108% of of original, as I found this is a good fit for a nut design.
