The model was exported with the free tool Mineways and printed on a Zprinter 650 3d-printer, with a block size of 125mm^3 (so every block has an edge length of 5mm). After printing, LEDs were glued into the case after filing the openings a bit wider. Then, the LEDs were soldered to form a 4x4 LED matrix, and the matrix was connected to an Arduino board.
