I'm still refining the design and am open to feedback, but all of the necessary basic elements are already there. If any brave souls out there have a ZeroCam & a 3d printer, I've made the prototype design available in our Telegram community:

Some additional detail: this enclosure is designed to utilize the smaller "ZeroCam" Pi Zero cameras that are widely available, & results in a significantly more compact overall form factor. It's designed to accommodate the same Waveshare LCD hat used in every SeedSigner build...

3d printing pro tip: hairspray can significantly improve bed adhesion. But it has to be hairspray that was popular in 80's or 90's. I don't make the rules.

Reduced reflection (on the right)
Production is right around the corner...

Looks like a *great* Specter-DIY enclosure design by -- very smart to disassemble the scanner module to create a more intuitive form factor. More details in this thread. 👇
