I ended up using an OpenSCAD blueprint by usedbytes to get measurements of the device. Reconstructed/synthesized a new case in Fusion360. Noticeable changes:
- A different battery holder / back pannel to simplify the assembly to some extent
- Two coin cells vs three
- Added hidden buttons inspired by Känner's design
- Back panel is inspired by Känner's design too, I like that connectors are accessible
- Battery toggle button
- Any mistakes are exclusively mine

Source code:
- To a large extent based on pimoroni Badger2040 OS example: https://github.com/pimoroni/pimoroni-pico/tree/main/micropython/examples/badger2040 (MIT)
- Font & rendering: custom code, but it is not worth extracting it to a standalone app/library. Let's stick with MIT for simplicity too.

Assets:
- Font: 16bfZX https://www.pentacom.jp/pentacom/bitfontmaker2/gallery/?id=246 (Public domain)
- Clippy: hand-drawn, I think the character is trademarked by Microsoft though.
- Other assets: hand-drawn

What does it mean in terms of license? I guess, it is good for a hobby project. Hire a lawyer to check if it is good for commercial use.
