The tiny 3007-fan of the Mini Afterburner is often not capable of providing sufficient cooling of the Dragon SF/HF hotend. One reason is that the fan only produces airflow around the edges while the heatsink of the Dragon is small and located in the middle. The heatsink is therefore mostly in the wake produced by the motor and bearing housing of the fan, where very little air is actually flowing.
This model, the DragonTamer, is a small air guide which forces the air from the fan to pass through the heatsink, instead of bypassing it. It also has a bottom plate to prevent the air from escaping downwards, towards the print.
I have uploaded two versions. One with openings for the cables from the thermistor and heater, and one without. The openings makes it easier to guide the cables upwards in the tiny space available.
Insert the DragonTamer at the same time as installing the hotend itself. The DragonTamer fits around the Dragon mount and has four prongs sticking out to keep it in place. It also fits in the Mini AfterSherpa, which shares the inside dimensions of the Mini Afterburner.
