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. Common values are 0.5mm and 0.35mm.
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, and consequently may
be a useful thing to do even if the diameter is known.
