this is a new approach for the stock Cetus3D printer. The fan will be mounted in line with the extruder motor. This setup will not have any part cooling option anymore!
DRAWBACK: The fan will only cool the top nozzle part to prevent it from jamming.
ADVANTAGE: you can print materials up to 285C (e.g. PC, ABS, TPU etc.) and further the extruder motor is actively cooled. This motoe reaches in stock use up to 60C. with this setup it stays in a range up to 40C even under heavy load.
WHY?
The stock setup is nice. PLA is printing fine but for special materials part cooling is not that important. With the stock setup the nozzle is cooled down too much so it is hard to reach temperatures above 250C. I use the postion of the fan for more than 2 years now without any problems with the pallet+ feeding tube.
Only issue I realized the air is getting away from the motor to the sides and cooles down the part. I usually used tape to close the sides. To control this issue I designed this cover. You can use the stock cetus fan. The extention board cover is quite useless in my opinion so I added a filament feeding tube. There is only one printed part needed finally to get the Cetus much more powerful.
