3M Filter - Hexagon Filter Capsule (No Text and Extended Versions)

thingiverse

Remix of alphaa's hexagon filter capsule for 3M 6000 series found here https://www.thingiverse.com/thing:4164053 I created a version without text and extended to hold more filter material. I'm using several layers of Filtrete filter material with an active carbon layer in between. If you plan to use only surgical mask or thin filter material, print the standard version. However, if you want to add active carbon or other filter materials, print the extended version along with the back cap. I also made a tighter adapter for those who find the original one loose. The new adapter is 0.25mm thicker and provides a snugger fit and seal. The filter material I used can be found in stores that sell home filters. Other brands should work well too, just ensure you get high-quality filters rated for bacteria and viruses, and static charged. You can find the active carbon/charcoal I use at pet stores or bigger chain stores in the fish tank aisle.
