3. Nozzle Diameter
The diameter of the hot-end nozzle is usually clearly displayed either in
the description of the hot-end, or in the associated documentation, when
the hot-end is purchased. The default nozzle size on the Mini hot end is
0.5mm.
If the nozzle was home-made, or came from a source without a diameter
given, then carefully measure the aperture as accurately as possible. One
way of determining nozzle size is to very slowly (1mm/s) extrude some
filament into free air and measure the thickness of the resulting extrusion

This has the benefit of taking die swell into account.
