Exclusively by TapTes, designed just for Tesla Model 3, designed by an American Tesla Model 3 owner & designer Vu Tran. Fit all Tesla Model 3 Vehicles. The Tesla M3 cup holders are wide and do not hold typical water bottles very well, the bottles may slide around and possibly tip over. Our Cup Holder Inserts will help to solve the problem. Hold commonly used drink containers well, cup holder inserts allow the bottles to stay upright, also work well for small coffee cups.  It fits small Starbucks cups, 500mL water bottles, and regular McDonald's cups. Inner diameter, top 2.75 inches to bottom 2.68 inches (70 mm to 68 mm), fit Tesla Model 3 center console cup holder. Made from high quality durable black ABS plastic, not cheap plastic feel. Match your Model 3 interior taste.
