a board with the word love and a battery holder and LED lights that, when lit, project the word love on the ceiling

It is best to print the LED container from a white filament and do not direct the light directly onto the template, it is best to use a reflector

the model was suitable for individual multi-color printing, even on a printer without AMS

glue needed 
battery 
switch 
and some skills

it does not show how it is printed due to a damaged printer
