Creality Ender 6 Hot End & Part Cooling Duct

thingiverse

Why design this accessory? The secret to no-clogs is good hot end heat sink cooling which in turn keeps your heat break (filament delivery path) cool. The factory fan mount allows air to escape everywhere avoiding going through the fins of the hot heat sink. This duct fits closely to the heat sink directing a skin of around the ends of the fins with the rest being forced through fin gaps. The factory pat cooling fan duct is marginal with only a tiny thin slit for air exit. Probably leading to the fan being stalled. The replacement duct relocates the fan to the operators left hand side of the hot end. The air chute is much larger allowing better flow from the fan. Be warned, I am an ABS printer. However, I wanted to preserve the cooling fan capability when I upgraded the hot end cooling and thus why I put effort into this part. Use your own experience to determine if it improves the printer with PLA or not. I welcome your test results and comments for further improvement of this part. Usability and Fitment. Uses all existing fasteners and fans. Fits the Creality Ender 6 Carriage. Uses existing screw holes. Fits with factory hot end.
