The narrow focus cooling duct is a varient of the generic triangular duct that came with the Anycubic Kossel builds and many other delta printers. This one has been designed to channel airflow in a tighter stream, not at the nozzle, but just above its tip, in a tighter stream. Instead of a larger duct, wrapping around the nozzle, it leave the area around the heater block open for other attachments, like probes, LEDs, and other useful extras. Still being tested, but the hope is for the focused stream to cool parts with more precision.

This is the newest version, with a broader opening and slightly thicker walls. I've also reduced the bend, so that it doesn't lean so close to the hotend.
