Fuel Pump Warning Light – 3D Printable Tag/Icon/Keychain

A minimal, bold warning icon for when you're running low — on fuel, on time, or on patience. Cleanly designed for two-color 3D printing, it works as a desk accessory, keychain, wall label, or just a reminder that something probably needs your attention.

Two-color print setup:

• Included: .3mf file with two separate bodies (base + icon)
• Compatible with:
• Multi-material systems (e.g. ACE Pro, AMS, MMU)
• Or manual filament swap using Pause at Layer

Suggested Print Settings (tested):

• Layer height: 0.16 mm
• Nozzle: 0.4 mm
• Material: PETG
• Infill: 40%
• Supports: none
• Brim: optional
• Ironing: on top surfaces only – makes the fuel icon smoother and sharper
• Pause at layer: ~15 (adjust per preview for color change)

Tips:

• You can scale it down to 65% in X and Y if you want a smaller version.
• Keep Z at 100% to preserve icon depth and sharpness.
• Looks great next to other warning icons — especially if your life is full of them.
