Description

I created a remix of 6markfuller and UD-HensNest's great designs. UD-HensNest's original design incorporated a snap ring system that was improperly scaled at the time. I recreated the ring to incorporate a couple upgrades for different scenarios. I increased the size of the nib on both rings and then created two more with an overall longer lip along the z-axis. I also created a "Ring Only" version which I recommend for general use. I optimized the geometry of the ring to print best using a .4mm nozzle at .32mm layer height. Purpose: This setup makes it easier to breathe as it provides more surface area by creating a tent over your face. I'll leave the medical benefits to having a "tented" face covering up to the medical professionals but it would be worth checking both 6markfuller and UD-HensNests submissions. Installation: Print one S/M/L sized mask, ring, and tent per person. Attach UD-HensNest's "squigglyspider" to one of 6markfuller's masks by placing the nibs of the spider through the hole on the anchor points. Then place a filter medium over the ring and through the hole on the squigglyspider. Use whatever rubber-band/string material you have to fasten it on the anchors. Advised to form a system that goes over the back of your head rather than fastening it to your ears as it's uncomfortable. I use three rubber bands tied to each other with the band on the ends looping over the anchor hooks.
