tolerance nut width not possible to adjust

[hstarmans]

it is not possible to add a margin to the nut width from the gui I need more tolerance as I 3D print the parts.

Current work around manually added a tolerance in get_screw_nut_spec in helper.py. I tried to change your code but although I like your module. Your code style suffers from a lot of boiler plate code... Look at the function; there is a lot of repetitive patterns.. The style is not optimal... Still I do like your module a lot 👍
