Hey! Recently acquired a K3, and tried searching (amazon, keychron website, some reddit) for a blank (no letters, no anything) keycap set for it, but didn't have any luck. I can't be the only one — did anyone find one?
Looks like the switches are MX-compatible, meaning most keycap sets out there would fit it. Look for XDA or DSA profile blank keycaps. Those will have the advantage of having no difference in profile between rows, meaning a key intended for the bottom row will still work for the top row etc. They can be found for cheap on Amazon or AliExpress.
