Just print a box, add the plate – print in variable colors to imitate LEGO logo. Then just buy a LED strip (IKEA worked for me), put it inside and glow!
Maybe a magnet will be needed to attach, i used a small 3 mm magnets glued onto the box and larger 10 mm magnets glued on the plate.
The author remixed this model.
LEGO logo in multiple layers instead of Recording sign.
