FlashForge Creator 3 Nozzle Fan Blanking Thing..

thingiverse

The FlashForge Creator 3 is capable of relatively high temp printing however it is not possible to turn off the nozzle cooling for high temp materials because the fan cools both the nozzle and the heat break simultaneously. This component blanks off the nozzle and re-directs all cooling to the heat break. This part is a direct swap for the two part fan duct, this fits the left extruder assembly only (likely just a mirror for the right although I haven't tried this yet). The 4 screws that hold the fan in place need to be removed to fit this, it's a relatively simple process. This design needs 2x M3 threaded inserts for the lower two screws. This has not yet been extensively tested however it fits my printer nicely. *This design has been revised after testing the previous version, there was slight warping of the previous design during long prints. This design moves the duct as far from the hot nozzle as possible.
