It's tiny remix of the original Voron 2.4 HEPA Filter exhaust
https://www.printables.com/model/323674-voron-24-hepa-filter-exhaust-wmagnetic-cover-filte
I just moved the threaded hole for the PTFE Tubing connector on right side and 45 degrees, so the PTFE tube is not on 90-degree angle when you have filament spool on right side of the printer.
Another small change is bigger hole in the filter adapter so more air should go through the filter and less stress for fan.
