I recently switched to the 3DVerkstan design of visor , apparently I don't have any photos yet, the arms and hooks are thicker than the schonne bakkes design so they tend to print more reliably. The indent on the visor brow makes it print just as quickly and the visor can be prepared from A4 sheets and a holepunch so they're easier to replace by the end users if need be. I did however have a request for safety goggles today rather than a full face shield. The schonne bakkes design conveniently already has a snap on screen tailored to fit closely to the face but also large enough to keep your glasses on. I ran a two pairs of specs out quickly today using some acetate scraps and they worked well. I'm still waiting for more sheets to arrive though before I can ramp up to some serious production.

The Prusa face shield took quite a long time to 3D print and I instantly started to think of ways to reduce that time. It wasn't long before I found this Schonne Bakkes design ( files are in their one drive ). It prints a lot faster because it's skinnier so I turned out a few of these for evaluation too. The screen simply clips into the 3D printed frame and doesn't need the bottom retainer to help it keep shape. The initial review suggests that the Prusa shape fits people slightly better so I'm wondering if I should mash the two designs together, I'm also still looking for a purely laser cut design that would be much faster that anything 3D printed.

With PPE  in short supply across the country, I showed my medical friends the Face Shields being produced by Prusa. They were interested in the design and fit so I printed out a few shields for them to try. It's printed in PLA, I went for the straight version because I was only doing one at a time, the screen is cut on the laser from 0.5mm PETG plastic (a little scratched from being on my shelf for years). The design works well, the band printed in 2.5 hours and the screen in 23 seconds so there is a little bit of disparity there. They were well received and I'm waiting to hear back if they would like some more, in the meantime I'm trying some other designs too and keeping my eye out for a purely laser cut version.
