Mercedes Cup Holder Phone Holder (Samsung S9)

thingiverse

I was looking for a phone holder that fitted into the cup holders in my 2012 E-Class Mercedes and couldn't find one so came up with this. Its got cut outs in the back so you can glue a USB Cable in to make it powered also but it works just fine without. It has the 4 cut outs that slot into the cup holder to keep it nice and tightly fitting. The only thing I found was when its used as a powered cup holder I had to velcro the cup holder down so it doesn't pull out when you remove the phone. This isn't an issue if you use it non powered. The hole for the phone is 72mm, this fitted my Samsung Galaxy S9 with its case on just fine but should fit other phones too. I've recently changed to a W205 C Class and it fits great in that too so will probably work in most mercedes cars with the 4 prong cup holder fitted.
