I saw some Minecraft cookie cutters, but I wasn't satisfied with the size or with how to hold them so I made a set for a friend. For those of you like me who worry about food safety, I printed them out of PETG but also coated them multiple times in a food safe resin (the same used for making cutting boards) so that it can easily be washed and reused. 

Handwashing them has shown that the coating is staying on, food is not collecting in layer lines, and also from what I could find from the most recent research that so long as they are in long contact (like storing food in a printed container) which cookie cutters are not, they are safe.
