COVID mask STRAP, EAR RELIEF SAVER

thingiverse

This version has a tighter fit compared to the standard MASK EAR SAVERS.\r\nI adjusted mine along the X axis to 120% for a better match around my head size. You can adjust your scaling accordingly, but 120% is usually a good starting point for adults.\r\n\r\nTo save on material, I also scaled down along the Z axis to achieve only three layers with a layer height of 0.4 mm.\r\n\r\nI added a new variant V3 where the strap points are positioned higher up. There's a trick to getting the elastic strap right - experiment by shifting it between the attachment points until the pressure feels even on top of the ear stem.
