// A development test for 2 private functions used by do_nuthole():
//   _get_boltz() returns the bolt carving deep in nut insert (doubled).
//   _get_nutz() returns the deep for the nut.
// This test shows the carving shapes makes by do_nuthole() for codes -1090 and -2090, for diffent support thicknesses.
// You can get the STL and make exact measures (the cube replaces the support) using netfabb, to fine tune _get_boltz() and _get_nutz() on hardware data.
// General rules: 
//   1. The thickness under the nut must be more than _minz but with a limit to mm 3.
//   2  If possible the nut and the bolt must be hidden on the opposite side.
