A little something to let other know what's up.
I have included an AMS print profile where you can change the colors of the sign, heart and letters.
I have included a profile with a pause after the base sign layer is printed. Swap out the color to print the heart and letters. Note you can only print with a maximum of two colors with this profile. If you want more, it would be too many pauses so just use the AMS profile for easier prints. This profile is for people without an AMS and still want a little bit of customizability.
It should scale to any size to fit larger door handles.
