COVID-19 confortable mask with standard HEPA CPAP Filter

thingiverse

This design utilizes standard CPAP Filter sold on Amazon. I suggest opting for the HEPA version. I secured the hard part to the flexible part using crazy glue from a dollar store. For the soft part, I recommend utilizing TPU and PETG for the other two parts. This mask is available in various sizes with high ridge nose HR and Low Ridge nose options. To enhance comfort, attach this behind your head: https://www.thingiverse.com/thing:4362103 When printing the flexible section, I advise using a 0.4 extruder with direct drive and 1mm retraction for optimal results. _____________ BEFORE DOWNLOADING PLEASE READ THE FULL LICENSE.
