About this 3D model
This is a switch support for car, bus... You just need a place where to attach a rope and make it pass through the 3 wholes of the support. (Like in the image) . It works great! After testing it 2 hours in car and 10 hours in bus I had a great experience. It gives enough space for the screen and at the back and bottom it has spaces for a cable and for ventilation. I also attach to this a top that I made but didn“t tested. It is ment to be attached to 2 wholes of the support.
