The 3D printing community around the world has united to 3D print face shields for those who desperately need them due to supply shortages. Unfortunately, the most popular designs aren't able to be printed on small 3D printers - which are the most popular size of 3D printer in developing countries. There is also room for improving upon existing designs by making them more inclusive and not one-size-fits-all.

What it does

Faceshield 2.0 is an improved version of the 3DVerkstan face shield. Instead of 3D printing a single component, you print 5 and them assemble them into a single component using screws, zip ties, or glue. This allows for the components to be printed using smaller 3D printers. Faceshield 2.0 also allows for manual adjustments so you can have a comfortable fit - which is important for those who are required to wear them for long periods of time.

How I built it

This project was created using Fusion 360 CAD, the test pieces seen on this page were printed using the Cocoon Create Model Maker 3D printer and assembled using a combination of screws and zip ties to demonstrate the multiple ways it can be assembled. The clear A4 plastic sheet was purchased at a nearby office supply store. The holes were cut out using a standard Australian hole-punch. A rubber band is optional and allows for a more snug fit around the head.

Challenges I ran into

It is important for the designs to be as easy as possible for other people to print using a range of different 3D printers. Choosing between simplicity and functionality was difficult but I believe I found a good balance. Further improvements can be made.

What's next

This new design should first be approved by medical professionals before it can begin being used. A range of designs should also be created to fit the many different international hole-punch standards.
