Simson Lightbox

I created that Lightbox by request.

Assembly:

Print the Front and the Back part. There are no holes in the model, just add the holes via Bambu Studio. It depends on your light strip or if you want to use a barrel connector. You can also just use a drill.
Measure the length of the light strip and then cut it to length.
Solder the wires and the barrel connector to the light strip
Mount everything into the front part
For the back part I used normal aluminum foil with some double sided tape to reflect the light. See pictures
Close the box
