Cupholder Phone Rest

Cupholder-mounted phone rest designed for pre-facelift 2010–2011 W212 E350 sedans. The author shows the physical print with the original cupholder and states that its open centre permits a charging cable while the factory cover can still close. Print in ABS or another proven cabin-heat-resistant material, match the cupholder and phone dimensions, route the cable clear of controls, and verify the rest cannot release the phone or interfere with the selector under braking.
