Just put these simple letters on your cake, pour powdered sugar or chocolate above it and then remove the letters. There you have the name of the Birthday Kid or something else on the cake xD.
The letters have also a little handle so its simplier for removing and placing the letters.
The g-code are for the MK3S+ with MMU3 but use in Single-Mode (only one Color). I uploaded also the stl and 3mf files.
PS: Made by me.
The author marked this model as their own original creation.
