💡 Check Engine LED Lamp with Dollar Sign ($) – WS2812B RGB Edition

A fun, geeky decoration for makers, car lovers, and anyone who's felt the pain of a glowing check engine light.

This 3D-printable Check Engine icon comes with a twist: instead of the classic engine outline, it features a dollar sign ($) – a humorous nod to what we all know that warning really means: "This is gonna cost me..."

🔧 Features:

• Easy to print – no supports required
• Multi-part design: separate front icon plate, back housing, and light diffuser
• Built-in cable pass-through and mounting holes
• Ideal for ESP32, Arduino, or any LED controller

🧱 Recommended Print Settings:

• Material: PLA or PETG

💬 Tip: For extra style, program your LEDs to simulate a “Check Engine” flicker or warning glow – red-yellow pulsing effects work great!
