The diffuser works perfectly. The LEDs look like pixels, and the brightness is excellent thanks to the use of white PLA. Many thanks!

Since I used completely different power connections (USB with breakout board) and a different ESP, I had to modify quite a bit from the original. In addition, I added a small toggle switch on the side to turn the matrix on and off. The frame around the model doesn’t hold perfectly and tends to come loose from the rest of the case. That said, as a basis for the matrix I built for my son, the model was very helpful! We are both happy about the result so: Many thanks for that! :)

Thank you very much for the model! I only printed the frames. Original sockets fit well, but the corresponding light switch buttons are unfortunately quite tight. Since I was only missing a few frames, I rearranged things so that the printed frames went where the original socket frames had been. I then used those original frames for the light switches.

A beautiful model, thanks a lot for your work. Unfortunately, the outer lines of the two parts don’t align properly. Because of the surface, the top and bottom slide so that one part’s outer line slips into the groove of the other. Lines intended to be straight and continuous always end up offset, which sadly doesn’t look very nice. A possible improvement could be to add a connection preventing slip or twist, e.g. a small recess in the bottom part with a matching counterpart in the top part.
