Ender3 Hotend with 60mm fan and led
thingiverse
I've upgraded the system with a stock layer fan and added a nozzle LED for improved functionality. Using the PSU fan, which is also 24 volts but has a 60mm size, I've opted for this choice due to its higher airflow compared to the original 40mm hotend fan. To optimize performance, I've reduced the voltage to 20v by connecting a 5mm white LED in series mode. This additional light enhances visibility near the nozzle. To securely attach the layer fan, embedding nuts are required; I employed a soldering iron for this purpose. The connection process involves linking it to the same plug as the original fan on the board.
