It looks like this changes the format of the model parameter from the motor definition structure to an array index. This isn't acceptable because it'll break many designs floating around the internet that use this module.

This echo shouldn't be here, I think.

| width = METRIC_NUT_AC_WIDTHS[size]+2*tolerance; |
This isn't really a radius any more.
