So how do you close the wind barrier?

Firstly i have always left mine half open so the air flows in one direction and never used it to any advantage, as i grow and learn more about certain filaments and cooling effects i may add more controls to the directed air to the print nozzle.

Secondly that slit on the front side(facing viewer) allows me to insert a tab all the way to the far wall that has a stop if i ever want to block completely the air to the nozzle. or punch a few holes to allow some air thru. I am not a fan of moving parts on an oscilating device (just my preference)

BTW the 1.5 mm gaps around the cooling block (black) is by design. I want some air movement to cool the cooling block amd above the heater. Maybe will keep the stepper cooler,

When i have time I will add a thin insulating plate in between the heater and the cooling blck. But i hate to add more weight to the head assembly and at this time i have no requirement or need to get the stepper cooler (im sure its better to be cooler) but maybe in the future

Balance between need and nice to haves
