Title: Fix hot end screw2

This branch takes into account the suggestion from the previous merge request.
The 3rd commit (6cb99e4) allows to keep a constant hole size whatever the chosen length of screw, and migth be removed.
Tested with “eyes” changing several parameters (jhead_total_length, extension_clearence, jhead_screw_pitch, …)
