Hotend Duct for Qidi Plus 4
Description
The Plus4 can sometimes suffer from Heat Creep in certain conditions. This duct/plenum attempts to better route the air from the intake fan over the heatsink to minimise the risk of heat creep for parts with many fine retractions, or at certain filament temperatures. By default, there's about a 10mm gap between the outlet of the fan, and the surface of the heatsink, and there's many paths of lesser resistance for the air to flow, instead of through the heatsink. This design is intended to be a snap-in-place piece that minimises the air-flow loss and better cools the heatsink.
