This is an updated version of https://makerworld.com/en/models/121699, with a clear frame line and more characters. Also better for printing in small sizes (Set wall generator to Arachne).

Use Magnetic Tape to make pieces stick to a fridge door and other metal surfaces, or create a suitable hole for button magnets by adding Negative Parts on the bottom.

Let me know in the comments if you need additional characters.
