That looks good to me and it will also be extremely useful
for all other types of 3D models (currently only IDF but
IGES is in development).  This would require a change in
the file format, specifically the addition of a unit type in the
3D model section, and I think such a change is best done
before the stable release so that people who adopt the
stable release aren't bitten by a pcbnew file format change
later.

I would use radio buttons rather than normal buttons and
perhaps change that unit to "0.1 inch" to serve the existing
models or even consider 3 sets of units: mm, in, 0.1in.
