I was hoping to watch the video below.

Current design: The JPL designer of the 3D printable COVID-19 Comfort Respirator describes the preferred design. https://youtu.be/vaxoGQcy00

If you have any comments or have tried one of these builds please let us know your feedback.
We are especially looking sizing and fit comments, or build issues.

Thank you!

Can't find it anywhere in the repo.

The default Cheetah-TPU.ini configuration file results in stringing and jamming when loaded for the Prusa Mk3s w/ Cheetah TPU.

I was able to get clean and consistent results after applying the following changes:

1. Disabled retraction
2. Slowed all speed variables to 20mm/s
3. Increased the extruder temp to 240C

To those unfamiliar with flex material (like I was before trying to print this), I recommend applying a glue stick to the work area prior to printing. Otherwise removing the print will likely result in warping or tearing.

Here's a photo of the comfort print after making the changes mentioned above.

I know the 4 designs are all a bit different, but not all of them discuss cleaning the mask. I'd like to see a document on that topic. (my mother-in-laws nursing home is asking me about cleaning these, as we try to determine if they will meet their needs).

Different applications can lead to different requirements. We have started to collect feedback from our local users and would like to hear from anyone that can have an idea or issue that we may be able to help with. Wearing a respirator might just become part of the norm for now so let's get creative and make the best of things.

Hope to hear from you!!

I believe that the meton-sellion length in the performance mask wiki picture (mask size selection) has a scale issue. I believe it should either be divided by a 10 scale factor, or set in mm (~102-125cm seems really big for a face portion).
