These are nice Vault-Tec-approved cookie cutters :D
Simply use a type cookie dough, cut out, tap the back of the cookie cutter when removing or lightly press the center when using the Vault-Door, then bake the cookies and decorate as desired afterwards. I have for this icing mixed with food coloring and the black contours with sugar writing in black applied.
Enjoy baking and decorating, feel free to leave a make or comment!
Print Settings:
Nozzle diameter: maximum 0.4mm
Layer height: 0.2mm
Material: preferably food grade (Food grade filaments for 3D printing include PLA, PP, PET, PET-G, HIPS and Nylon-6, as well as certain brands of ABS, ASA and PEI. If the product needs to be dishwasher safe, PET, Nylon and PLA are out of the question, as these plastics soften and deform at 60-70 °C) --> pay attention to the manufacturer's specifications!
