Bambu Lab Chamber Fan Cover - Compatible with AMS HUB

Hello Everyone 

I am sharing a model of the chamber fan cover of my design. I tested other models but found that they significantly reduce airflow. In my opinion, this may cause the fan to wear out faster and the return of fumes to the inside of the printer where the electronics are located. The closed fan cover does not significantly increase the noise reduction. That's why I decided to design my own cover. I made 3 models and after testing I chose the best one and share it with the Bambu community :-)

When you complete the project, please share a photo and a comment. Thank you and have a nice day.

Update 16.06.2023 :
At the request of the community, I added a version for different dimensions of the magnets. From today, the V2 version is available for magnets with dimensions of 4x2, 4x3, 6x2 and 6x3mm. For magnets with dimensions of 4x2 and 4x3 I have not conducted tests. I don't know if they are strong enough to hold a Fan Cover. I recommend using 6mm Neodymium Magnets.

Update 12.10.2023 :
I added another version, this time for 8x2, 8x3, 4x2x6pcs and 4x3x6pcs magnets
 

Characteristics :

• Cover highly reduces noise from the Chamber fan (Especially when it is set to 100% speed)
• Compared to others, mine is compatible with AMS Hub
• The inside is rounded, which allows free air flow
• Added ribs that evacuate air faster
• The bottom of the cover is open so that it does not create a vacuum and does not cause the vapors to return inside as in other models
• Simple Magnetic Mounting
• Easy positioning - Left edge of printer and bottom of AMS Hub
• Design Features the Bambu Lab logo

You can download the STL file that needs to be colored and the 3MF file that is ready to print and is in color (Just change the filament to Your color). For the project you need 4 Neodymium Magnets with dimensions of 4x2, 4x3, 6x2 or 6x3mm. I recommend using 6mm Neodymium Magnets. In the color printing it is best to set the model horizontally as in photo with Bambu Lab Studio. You can also print vertically then the inner walls are perfectly smooth. However, I do not recommend this when printing in color because it uses too much filament. Do not buy a ferrite magnet because it is too weak.

How to print ? :

• Material : Any
• Layer Height : 0.2mm
• Speed : All Max 120mm/s
• Infill : 20%
• Wall Loops : 2
• Top Shell Layers : 3
• Bottom Shell Layers : 3
• Support : No
• Brim : No
• Brim Auto : No (Be sure to disable Brim Auto. When printing in color with Brim Auto on, it may cause a problem on the first layer)

Version :

• In the V2 version I added ribs and I changed the holders of the bottom magnets.
