Surgical mask strap

Credit to MARSLAM for posting the original version.

This mask strap helps to eliminate ear strain from wearing the mask for extended period of time. It has multiple loop points to accomodate different head sized.

This new model includes round edges so that the part will come off the print bed cleanly without sharp edges.

If you have an 8"x9" printer, it is possible to print 8 pieces at a time that takes about 2.5hrs to 3.5hrs depending on the setting. Recommended setting as follow:

Layer height: 0.2mm
Infill: 25%
Material: PETG
