I'm actually interested in this, but I'm concerned that they don't show any pictures of the finished cookie. The Optimus one in particular looks like all the details might turn into a vague blob when cooked.
My experience with highly detailed cookie cutters like this is that there aren't many cookie types they work on. There are too many places for even mildly sticky dough to get stuck and make it impossible to release the cookie without damaging it. You have to make very dry sugar cookies for it to work, and preferably spray some release agent on the cookie cutter first. So they look good, but don't taste great.
FYI: if these are 3d printed, they aren't (at least yet) considered to be food safe. If you're ok with the risk, so be it, but be aware of it nonetheless.
