Nozzle fan duct
thingiverse
This is a precision-designed nozzle fan duct for high-performance 50 mm radial fans, expertly mounted on my previous bowden extruder mount. Check out this game-changing design at https://www.thingiverse.com/thing:2766948. I've experimented with various duct options, including circular and double-sided designs, but I'm convinced that this is the most effective solution yet. To take full control of your nozzle fan's operation, simply connect its power cables to the D9 (12-volt) connection on your ramps board, allowing seamless software management.
