Printable Threads 45 (special threads for 3d-printing)

### Printable Tread ###

Special threads for 3D-Printing:
Let's call it Pt.

Main idea:
Pt6 has nominal outer diameter of the screw thread 6 millimetres, after printing.
The 3D model must be adjusted to be right after the printing, so in the real world all threads are compatible to each other.

Pitch = 2.0 mm for each thread.
At least 2.0 mm is needed for the standard layer height 0.2 mm, it gives 10 layers for one pitch.

The 3D-Printed screw has nominal diameter:

Screw-6 has real 5.9-6.0 mm outer diameter (in model it was 6.2 mm).

The list of dimensions:
