I created a Fiat Lightbox.
If you have the problem that the parts don't stay together, print Version 2. The 5th Layer is an support Layer. It helps to connect the objects.
Version 1: The Logo has 4 Layers
Version 2: The Logo has 4 Layers + 1 Layer white that helps to keep the Logo together
If you like my work and want to support me then feel free to buy me a beer
Electronics:
I used a 12V LED light strip, a DC barrel connector, a 12 V power supply and some wires
The power supply and the DC barrel connector I used
