Silicone Head Strap – University of Oklahoma
Machine:
Laser cutter
Material:
Silicone rubber, ~1mm thickness
This silicone strap, designed by Tyler Thibodeau, senior tech lead, Tom Love Innovation Hub, will fit virtually all of the open source face shield designs available - certainly all available on this website. The silicone is thin enough to stretch, and has simple holes for adjustable sizing.
This simple design has received more positive reaction from our healthcare professionals than any of the other designs because of its comfort. The silicone can also be cleaned and reused.

Cleaning process
The straps will likely be covered in soot and ash from the cutting process. Some of the small holes may re-melt and cool together. These need to be cleaned before delivery.
We soaked our prototypes in 5-gallon buckets with a healthy amount of regular dish soap and hot water. Then, we used a length of scrap wood to stir and agitate the straps for several minutes.
Rinse the straps clean of soap and then hang to dry. These straps pair well with many commercial face shields including the designs listed, here.
