About this 3D model
This is the Bambu Lab lithophane frame. I cut off the top and added connectors (in Bambu Studio) for a easier print with less support. I also removed the Bambu Lab lettering to lay the top flat on the build plate. Use some glue and put the pieces together. This frame is for Bambu CMYK LED Backlight Board (156mmx120mm) , not for Lithophane LED Backlight Board Kit.
