parameterize nut flat width, echo thread specs #10

Closed stevegt closed 5 years ago

stevegt commented 6 years ago

Different thread sizes have different proportions of nut flat width versus thread major diameter, so we shouldn't base nut flat width on sheet thickness. This change adds an optional fourth element to the captive_nuts array, allowing the user to specify the exact nut flat width. If the user doesn't specify a nut flat width, then we default to the legacy behavior of (3 * thickness) to preserve backward compatibility.

Regardless of whether the user provides a nut flat width, we also now echo the thread and nut specs to the console at compile time, to aid the user in selecting hardware.

Look good - will have a look when I am at proper computer. Thanks for your input
