This is an updated version of a Surgical Mask Tension Release Band that works for people with short hair and doesn't slide down. The need for this was discovered from feedback on this existing tension release band: https://3dprint.nih.gov/discover/3dpx-013410 This updated design uses two narrow bands to create a more effective cradle for the back of the head. It is adjustable to fit different sizes using a print-in-place hinged latch.
No support material is used. After print completion, use a blade to peel off the bed. Prying at the corners of the hinge features works best to get it started.
This will print two indentical subassemblies that need to be snapped together using print-in-place hinges. This allows for the adjustability to fit different users. For more detailed instructions see: https://www.2020dn.com/news/open-source-designs-for-covid-19-ppe
