If you are wearing glasses and you often need to take of your FFP2 face mask, you can make life easier with this small connector. It keeps the strain of your ears, does not collide with your glasses and you don´t have a mask dangling on your chin while it is not needed.

It prints within 15 minutes - strong enough to do the job and light enough to not add unnecessary weight.
