Try out this updated version: https://www.thingiverse.com/thing:4386053 This is Revision 2 of the original design, an improvement over the first revision that struggled with a strap slipping down the back of the head, placing extra pressure on the top ear. Revision 2 features comb-like ridges to keep the strap firmly in place on your hair. Those with very short or no hair might prefer sticking with the first design if these ridges cause discomfort.
