+- https://www.thingiverse.com/thing:5320100/files (CC4)
+
+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.
