About this 3D model

I have ordered several Hotends but you need a separate fan for each one... I thought to myself that there must be another way... with this duct and holder you can screw the fan directly to the head. all you need are 3 M2x4mm screws. You can then simply screw through the ventilation holes on the side. Be careful not to scratch the carbon guides The duct has the further advantage that now the whole air flow of the fan goes through the cooling fins and cools even better...! I recommend: - PETG or more heat-resistant material (definitely not normal PLA) - the result is best with a 0.2 nozzle A friend made a video about ++ one fan for all hotends ++ if something does not fit or you have ideas on how to make it even better, please contact me
