12-14 mm inner diameter threaded brass lens tube/mount? Where to find, who can make?

I'm looking for some brass threaded lens holder/tubes to mount some 11.0 mm outer diameter aspheric lenses in, does anyone know who makes the M9*0.5 lens holders we use which hold a 6 mm diameter lens and fit a standard 12mm module? I'm hoping if I can find the people who make those, they might make some larger tubes for me. Maybe someone already makes such a lens holder for a larger diameter aspheric lens?
