I've also been idly contemplating 3D printing braille. Somewhat annoying that that's the cheap+easy option, but if it works...

I 3d printed a coffee can holder for bicycles with the braille "coffee", so when you're riding and you reach down for a drink, you know which one is coffee.

The product didn't sell well, but it made good gifts!
