Laser Warning Holographic Effect Sign

This sign is designed with raised linework to create a holographic-style optical illusion, making the “Warning: Laser in Use” text stand out at different angles. It’s bold, functional, and looks awesome on the wall or near your workspace.

Perfect for makers using machines like Bambu Lab’s new H2D 3D printer with the swappable blue laser module—this sign adds an extra layer of visibility and style to your setup.

Prints flat with the option for a two-color filament swap (pause built in!), and works great with bright or high-contrast colors to make the warning really pop.

Stay safe—and make it look good while you’re at it.
