I stumbled upon this site with a lot of likely stolen models on it. It appears to be a small boutique that sells products by their vendors. One of their vendors appears to be violating the licenses of lots of models. (I don’t blame the boutique, they most likely aren’t aware of the problems.) If your models are on there and they aren’t licensed, I’d recommend contacting the boutique (there’s a contact form on the homepage) and letting them know. None of my models are on there, but I just figured I’d let you guys know. Some of them do have commercial licenses (e.g. the fidget joystick), but no credit is given (one of the joystick’s commercial license terms).
In the process of finding some of the designers from the site above, I also found these:
https://aline3d.com/ (and https://www.etsy.com/listing/1569348555/cute-3d-printed-axolotl-toy-hand-painted)
https://www.etsy.com/shop/CoastlineMaker.
I’m not sure if they’re stolen, as I can’t find the source of the models. I did find other people selling the same Axolotl, so I don’t think they’re original models.

Let me know if you find anything about them!
Hope this helps
