This is a mounting bracket for a Tomtom rider to be used with RAM mount stuff.
The reason for this bracket, is that the main bracket is on my motorbike,
so i needed an extra bracket to use in my campervan. The main bracket has power integrated, but with this bracket i use the USB connector to power the device. For short trips it will happily run of the internal battery though.

I printed this bracket in PETG with 50% infill, no support needed. I wouldn't recommend PLA because it would probably deform when left in the car on a hot day.
The design is in OpenSCAD (free software), so easily modified if you want to.
