Doh!

0,35mm nozzle print head on my 3D printer fell apart, from unknown reasons, just before I wanted to print parts for JJ Tricorder case. You know, Murphy's laws. I had one spare, however with higher diameter, something like 0,6mm or so, but I had no other way, so I installed new (old) one and started some calibration prints.

Julia worked on case design in the meantime.

I printed the plastic parts of case

And here it is, when idea comes physical. Yep, that's CRT display.

The same case, while waiting for button caps to print out.

Now I'm working on firmware. Basic functionality seems to work, tomorrow I'll upload here more photos of tricorder in action, maybe some video, and design files on GitHub.

Well, it's not far from one clock in the morning, time to save everything, backup and sleep. Monday mornings are always hard.
