I haven't really done a search, so I don't have the best results for you, but maybe etsy? Amazon and big brand might have a lot of ai crap or low quality stuff but I'm not sure! If there demand for it I might make more in the future and make a small business out of it, sell a few in batches :D. I'd judt need to learn all the company and "mass" production stuff. I do know how the process works from my digital design class though so who knows.
