If can't find anything but wood, then you could consider clothing it, like a chair. You could add some foam in there, choose cloth that fits your build, have a field day!

There's generally a lot of custom wrist rests you can find on Etsy.
I saw Etsy but the entire site gave me a "scam" vibe. Do you have any personal experience purchasing on Etsy?
Grifiti wrist rests are pretty solid. I like the fat one.
Thank you for your recommendation. I looked at some reviews and the Grifiti wrist rests look for like a good fit for my Keychron K6, thanks a lot.
