Face masks are usually attached to the ears. Wearing masks for hours can cause discomfort and even marks behind the ears.
This piece allows the mask ...to be held in the back of the head so that continued use will be more comfortable.
The piece lacks homologation but has been tested by health personnel with good appreciation.
If the printing is done with flexible material, the piece can be used as soon as it is printed. In my case, I have printed the flat piece, so it needs to be shaped after a more detailed explanation in the printed 3D.
