Adjustable and Flexible Mask Harness

I had printed several of the single-band ear strain relief bands in PETG for my coworkers, but discovered they were cracking from usage. They also were not working out for my coworkers who wore hearing aids, glasses, sunglasses, hats, etc. and sometimes did not provide a secure enough fit for their needs.

I designed this to be printed in TPU or other flexible filaments to accommodate my coworkers who were having a hard time with the single strap design. This design is very low profile and highly adjustable - if you have a weirdly-shaped noggin, it can probably be made to fit you. It's also flexible enough to fold up into a purse/pocket/bag with the mask.

The bands are 1mm thick, so they can fit under a hat. Completed weight is about 5 grams. The "buckles" that attach to the ear loops on your mask can be repositioned to a higher or lower anchor point to accommodate hearing aids, glasses, or other needs. The two main "bands" can be tightened on the lower and upper portions in
