You mention imperial size,but what with the rest of the world who aren't
able to find, let say a 4-40 screw.
If it is to be used with a nut, will be ok, can be replaced with a metric pair,
but if it is to be screwed in an already threaded hole in the printer's body
will be a big problem.
BTW, very good design!
