We started off 3D printing the open source RC2/RC3 face shields designed by the fantastic PRUSA, but quickly realised it would take too long to make the number we needed. We redesigned the visor for injection moulding – and then added some more improvements along the way to make the frame fit better, be easier to clean and last longer.
We donate and sell (very cheaply) our visors as well as making our designs open source.
