This thing is a cellphone holder that sits inside a cup holder in the car. It has 3 axis of motion to bring the cellphone to the best position.
I put some office rubber bands on the holder to create more friction to hold the phone better in place.
The two holders are connected with an office rubber band in between them, using the slot in the back of them
Note: PLA is not recommended in the hot areas, as it will deform in the heat in the car.
