Don't print the braille document directly. Instead, I suggest printing a braille embosser. Think Gutenberg press. Then use that to press braille lettering onto a sheet of paper.
Although if you just want one sheet, I guess you could use the print directly, but maybe don't use PLA since it'd be kinda sharp and unpleasant to run your finger over.
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!
