Ender 3 Hot End Heat Sink Fan Shroud
thingiverse
Hot End Cooling Correcting Duct remix to make it fit on my hot end. This focuses the airflow output by the fan blowing at the heatsink to only blow at the heatsink. Normally, the fan would blow freely blow at the heatsink with a lot of the airflow directed downwards to the heater block and nozzle. This mod forces airflow to pass through the heatsink fins, increasing cooling efficiency which helps prevent clogs. Fixes: Original was too thick for the stock screws - lowered thickness Heaterblock with silicone sock pushed against the duct - raised wall Print with supports on buildplate or just try without it and see if it works, uses very little plastic anyway
