Core One intake dust filter (lọc bụi cửa hút Core One)

I designed a dust filter for the Prusa Core One. I wanted to make it compatible with the beacon ventilation knob by @Biomech so it has a hole in the middle to fit around it. Without the knob there would be some modification necessary. Maybe ill add another version later.

The filter uses two 120x120x1.7 mm air filters for computers. The surface is big enough to not block the airflow. The filter elements are put between the bottom and top parts and everything is hold together by six M3  bolts. The whole filter is connected to the printer case with two M3 bolts instead of the snap rivets. 

Additional material:

• 8x M3 5 mm bolts
• 6x M3 washers (recommended)
• 2x M3 nuts
• 2x 120mm air filter

Update: 25.10.2025
I added v2 of the model. It has no hole for the ventilation knob so it fits a stock core one.
