I created that lightbox by request.
If you have the problem that the parts don't stay together, print Version 2. The 5th Layer is an support Layer to help the parts stay connected to each other.
Version 1: The Logo is 4 Layers
Version 2: The Logo is 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
