Core One L Exhaust Filter

This is a remix of this model: Core One Exhaust Filter


I found many vendors provide quality Tesla Model 3/Y cabin air filters at reasonable prices. Many have activated charcoal.  

The frame attaches to the rear of the printer via four M3 screws which thread into existing holes on the back panel (just outside the perimeter of the two fans).  The filters I have used fit snug enough to not need the retaining lid, but the lid can be used and secured with M4 screws.

Adjusted the position of the fan cut out to fit the Core One L changed fan placement in relation to the screw holes
