I know there is one seller whose business model is based solely around printable cookie cutters, and they have A LOT, but I have never seen them outside of the seller page. I also haven't search for models much lately, so I might just be missing them. Since they are $3 each, one option is to set your price filter to $4+.
Also, is it possible you are just searching through the "new" models? Because it looks like they uploaded a new batch this week. They will filter out in a few days. I've noticed that kind of thing happens sometimes when sellers finish big products with multiple variations or mass upload a library or models.
@miaomaio3d, they are 3d printable. https://www.cgtrader.com/gleblubin Honestly, if I had a 3d printer and knew how to bake I would definitely get some :p
