Hot End Cooling Enhancer Adjustment to Fit My Hot End.\r\nThis directs airflow output by the fan blowing at the heatsink to only blow at the heatsink. Normally, the fan would blow freely towards the heatsink with a lot of airflow directed downwards to the heater block and nozzle. This modification forces airflow to pass through the heatsink fins, increasing cooling efficiency which helps prevent clogs.\r\n\r\nImprovements:\r\nOriginal was too thick for the stock screws - reduced thickness\r\nHeaterblock with silicone sock pushed against the duct - elevated wall\r\n\r\nPrint with supports on buildplate or try without it and see if it works, uses very little plastic anyway
