Just a Panda Cookie Cutter I made for a friend's birthday.
As with any 3D printed object used for food preparation, I do recommend using some kind of smoothing technique on the final print. This seals the final product and keeps food bits out of the tiny spaces.
I printed mine with ABS, and used the acetone vapor technique. I basically bought a cheap stovetop steamer, dropped a bit of acetone in it, then put the part in the steamer for abotu 30 seconds. Then I let it sit on a glass counter for all the acetone to evaporate off.
