The file 'Glowing Letter H 3D Printer Model' is (stl) file type, size is 20.4KB.
This is an easy beginner project into electronics and 3d-printing. It can be made in just one day and is forgiving to manufacture while being a great decor.
Feel free to remix this design into other letters, this was just my specific use case.
The visor could be lasercut, but a 3d-printed one works good enough.
It uses warm white LEDs for 5V with onboard resistors.
