COVID (Montana) Mask, DAR filter adapter
thingiverse
(04/19/2020) I've added a simplified version which I personally use and it works fine. A tee connector will soon be available if one filter isn't enough (for example, for older individuals). This simple adapter can connect the DAR/HME filter to the COVID-19 Montana Mask. Credit goes to Dr. Spencer Zaugg and his son Colton Zaugg for designing the original mask. I also utilized a part of this connector from https://www.thingiverse.com/thing:4236194. Please be aware that this adapter hasn't been tested or approved by any authorities - use at your own discretion.
