This panda with built-in leds looks great on any wall. The ground pieces are screwed into the wall (there are some holes already in the model). On the inside you can install your Led strip. I used some govee RGB IC basics strips. They fit perfectly so that each segment of the strip is in a segment of the Panda. Then you can glue the middle pieces on top and as a last step you can install your covers. I put some aluminum foil underneath the Panda to spread the light evenly over a segment.

My print settings

For the ground pieces I used black pla, 0.2mm layer height, support and 15% infill.

For the middle pieces I also used black pla, 0.2mm layer height, no support and 10% infill.

For the covers I used white pla, 0.1mm layer height, no support and I only printed three layers so that the light can easily get through, but you can print it thicker if you want to or you can use transparent filament.

If you have any other questions, feel free to ask me.
