This remix adds an inside border to the diffuser in order to hide the LED light source points + add the same time it adds strenght to the only 0.4mm thin wall as required for this design.
suggestion : since the infill is very slightly visible as it is lit from the back by the LED lights, I used honeycomb infill which resembles the overall hexagonal shape and is therefore not ugly, and even looks as a part of the design
