VW T4 phone holder

Phone holder attachment. 

Fits the square hole above the ash tray. It has a 17mm ball where you can attach your phone holder of choice, should be pretty universal. 

You can keept the little plastic insert in the original position (Made so I don't loose it.)

No need to drill holes. 

Printing as shown in picture.

I used tree support for the front edge and the ball.
