Uber Car Topper, Lighted or Unlighted

Uber Car Topper (3D Printed + RGB LED + Magnetic Mount) 

Boost MeBoosting me helps me to spend more time in the 3D print world designing cool things, and less at my daytime desk job. Isn't that how we ALL want to spend our days? Thank you for your support!

Bring your rideshare game to the next level with this sleek, dual-color Uber Car Topper, designed for the Bambu Lab P1S. The dome prints in white and black PLA, diffusing light beautifully from the WS2812B RGB LED strip inside.
 

The design features a 15 mm USB-C pass-through, space for looping an 18-inch LED strip, and a black PLA base that secures to your car's roof using 110 lb-pull neodymium magnets — tested to be stable up to 80 mph.
 

Assembly takes under an hour: print, install lights, glue magnets, and seal the dome to the base with four drops of superglue. When powered, the topper glows clean and bright — perfect for Uber drivers who want extra visibility. 
 

Safety Note: To stay compliant with vehicle lighting laws, avoid programming rapid red or blue flashes.
