As I bought my car there was an existing holder for a special mobile navigationsystem. The reasons for this project is simple: no more update for it! So I checked the possibilities to create a holder for my mobile phone and I disassembled the old one. After some measuring of the basic plate (picture 2 and 3) of the dashboard I started to design it in Fusion. The idea is to install two separated parts (you need only 4 countersunk screws with nuts M3 x 20 to fixed them together). The "bed" (I hope that the right word for it) is exchangeable. At the moment I created a version for a Samsung Galaxy S4 but it has some issues with the camera and the volume up button. Next version has an USB connector in the middle of the basic holder, and it's black.The material is ABS and the current version contains a lot of bars to rigid the structure against vibrations and heavy hits during driving. During the firt printing I used a lot of support material for the basic part (for the next I'm going to avoid it). The bed has only in the corner some support. The temperature is for the extruder 235°C to 230°C and for the bed 120°C. Thickness of each layer is 0.2 mm.
