Proper Surgical Mask Strain Relief Band Placement
Ensure that the surgical mask ear straps still pass above and below the ear while the “Ear Saver” is worn.
Rapid Manufacturing for COVID-19
Gary and I have been producing both laser cut and 3D printed ear savers for medical and emergency personnel.
Both of these designs were given to the Saskatchewan Health Authority and 3SHealth and distributed for commercial production for medical personnel across the province.
Our manufacturing concluded with the end of the pandemic, feel free to use and distribute the designs below if you still need some ear savers

Where Our Dontations Went
Our PPE was sent to first responders and medical facilities across western Canada with a few facilities in the United States and Central/Eastern Canada to cover shortages at other maker spaces.
We collaborated with a group (the Saskatoon Earsaves Alliance) to help other makers and engineers optimize their designs/printer settings, and centralize requests.
Gary and I collaborated with nurses, doctors, and the Saskatchewan Health Authority (SHA) to establish approvals and SOPs, allowing our designs to be used in hospitals and medical facilities.
