Or a 3d model to print. Do you know of anything like that? Any pointers appreciated.
Not sure if it’s purely OCaml merch (as they serve as advertisements for their respective companies), but a lot of the tshirts produced by Ahrefs and Jane street and distributed at conferences often have camel-based artwork on them. I have a nifty one from Ahrefs for meta-OCaml and it has a camel wearing a top-hat.
