The HEPA filters main purpose is for noise attenuation.
Use the “FILTER_BLANK” if not using the filter or use “FILTER_SOLID_ATTEN_BLANK” (untested) and print w/ 11% gyroid infill, 0 top and bottom layers to add some noise attenuation.
*Design was inspired by the BRS Engineering CF80 and lines up with the PMB upgrade (not required).
