~ 3d design
A 3d model against the mask pain.
This 3d printing should reduce the ear pain caused by mask.
During the Covid-19 emergency, intending to reduce the ear pain caused by wearing the mask for several hours, I designed this ear saver that can be 3d printed in a few minutes. If you want, you can download the 3d model .stl from my Thingiverse page.
