This fan duct/spacer replaces either the old black one or the white spacers (picture) depending on your Qidi printer. It should work on Qidi X-Max, X-Plus and i-Mate (S) no matter if you are using the standard version or the high-temperature direct drive extruder.
My intention was to canalize more air towards the heatsinks instead of wasting it in all other directions.
