This is a revision to the mask strap that I first saw in a recent news story (Quinn from Canada). Same function, but with a little more love.
Adding a single and 6-pack print (fits on Ender 3 bed) STL file.
UPDATE 4/19: I added another STL file with remixes of another design I liked. Just splashed a little extra love on it. I'll credit the original designer shortly (need to find who did it). So, I finished printing it and have concluded that this design works best with thin (lightweight) elastic bands. Our masks have 1/4" thick elastic bands and they need the bigger hooks (as in the original strap). See photo for details.
UPDATE 4/21: I found another design that looked good called EarSaver. My Ender 3 could not get the initial layer to set (stick) to the bed properly. I eliminated some of the complexity and it prints fine now. Same settings for all designs.
UPDATE 5/3: Finally, I was given an actual surgical mask to test out these strap designs. Realized that many of them are much bigger than necessary. So, here (MaskStrap-v964) is a nicely sized remix of SamC-E's design. Same print settings as others. Single, 6-pack and 20-pack STL files included. 20-pack fits inside of a 200x200mm footprint.
0.35mm layer height and prints solid (no infill). Initial layer height is 0.25mm Printed with success in PLA on an Ender 3.
