Precision Adjustment Ear Saver
thingiverse
Having a precise adjustment will help to have an effective and comfortable seal that is not too tight or too loose. Easy to print (no supports) and holds very strong at any desired length between 88 to 130mm. Prints in two parts and snaps together nicely. The two parts slide together only on the edges so that hair doesn't get caught. **2020-04-10 Update:** I included a longer version (es2LARGE.stl) for mask straps that are not as stretchy. **2020-04-13 Update:** I redesigned and included a version so the arms are on a 10° angle. This may help keep the straps from touching your ears. **2020-04-19 Update** Added a version that is angled with two hooks on each end. Here's a video on how to use it: https://www.youtube.com/watch?v=Pz3pbHuUYiw
