Description
A classic “Check Engine” warning light icon turned into a 3D printable keychain or hanging tag.
Perfect as:
- a funny gift for mechanics and car lovers
- a keyring accessory for any driver
- a little wall or rearview mirror decoration
- a sarcastic reminder that your car might not be okay
Designed for dual-color printing – the body of the icon is dark (like black or gray), and the engine outline pops in a bright color (like warning-light yellow).
This model is provided as a .3mf file with two separate bodies (base + outline), ready for:
Automatic filament switching (e.g. ACE Pro, AMS, MMU)
Or manual pause-based switching – just insert a Pause at Layer command before the outline begins
Tested Print Settings:
Material: PETG (The Filament)
Nozzle: 0.4 mm
Layer height: 0.16 mm
Infill: 40%
Top Surface Pattern: Hilbert Curve (because I like it)
Supports: Not required
Brim: Optional
Filament swap: Pause before color layer (15)
