Proto Shield by Mat Thorne and Devin Montgomery 

The Proto Shield is an open-source, low-cost, quickly produced face shield. It is designed to be functionally equivalent to the Prusa face shield. It’s just 100x faster to make. The visor is compatible with 3D printed Prusa parts.

Materials for the Proto Shield cost less than $1, and it can be produced by almost any laser cutter in less than 1 minute. It can be stored and shipped flat, is comfortable enough to be worn all day, and can be disassembled for sterilization and re-use.

One person can make hundreds of Proto Shields in a day from almost anywhere in the world. Here’s how:


Laser cutter (40 watt+; bed size 10″ x 16″ +)

Hot knife or scissors

Small flat head screwdriver

Rubber gloves, face mask, and disinfected work surface


.060” or 1.5mm PETG sheet (approximately 16” x 2” per shield)

.020” or .5mm PETG sheet (approximately 9.5” x 9.5” per shield)

.75” or 20mm elastic band (approximately 14” per shield)
