Your car has a Check Engine light. Why shouldn't your body have one?

This funny “CHECK LIVER” 3D printable sign puts a humorous spin on the familiar automotive warning light. It's a great conversation piece for a home bar, garage, man cave, workshop, office, or party space.

The design uses multiple colors printed flush with the surface, rather than raised lettering, creating a clean, professional-looking finished sign. The lettering can be printed in transparent or translucent filament to create a backlit effect when LEDs are placed behind the sign.

Printing Features

• Designed for FDM 3D printing
• Flush multicolor design — no raised lettering
• Designed with translucent/transparent filament in mind. Highly transmissive filament may work too
• Add an LED strip or other light source behind the sign for a glowing warning-light effect

Make It Glow

For the best effect, print the lettering or illuminated sections using transparent or translucent filament and place an LED light source behind the sign. The result looks like a giant automotive warning indicator — except this time, your liver is the one asking for attention.
