40x40x20mm Part Cooling Duct for S+E Titan Kit

thingiverse

For use specifically with the Titan Extruder kit from S+E, designed for the Original Prusa i3 MK2. This custom mount enables the use of a larger 20mm thick 40x40mm axial fan as a quieter alternative to the standard radial blower fan. I discovered that 10mm thick 40x40 fans lacked sufficient pressure to cool properly. My Noctua A4-20 PWM fan is still on its way, but based on specifications it should work well. I've printed the part without support in PC-ABS material. There are two STL files available, differing only by a split channel that aims to guide air flow along a straighter path to freshly extruded filament. The other part closely resembles the original S+E axial mount. STP and X_T files are also included.
