Cube 3D printer community

Hello Dan,
I made a first test run. (See YouTube link below).
What you see:
Grid for the inlet of the Extruder and cooling fans removed (less noise)
Switches for the cooling fans.
Power supplies 19 volt (electronics) and 12 volt for the cooling fans.
Big holes in the housing for cooling air outlet and adjusting the stepper motors current.
With this low printing speed the printer is very quiet. The temperature of the steppers is quite low so think I don’t need cooling fans for the steppers.
What I would like to know is the nozzle diameter of the hot end, do you know that?
