Yet Another Ear Saver
Another mask strap I quickly whipped up in Tinkercad. I felt that most designs are a bit too flimsy. They tend to break easily. This one is a bit chunkier, shouldn't just snap. Designed completely from scratch.
For added comfort, you should preshape it with a heat gun to fit the back of your neck nicely.
Feel free to sell printed versions of this strap, I don't mind.
