Good timing

I just started designing a 3D model for a wide (4"+) insert into my 1.5's shelf area last week.
My idea is to basically mostly hollow this insert out, and make it into two conjoining halves seperated by a powerful spring, so that I can compress it to put it in the dash, and then after you stop compressing the spring, you have a perfectly-contour-fitting rock-solid platform to mount things in the car. Which, in my case, will be an integrated Nexus 5 + magnetic wireless car charger in a 3d printed car dock integrated in this platform. Also going to sand this down to make sure it's very smooth, wash it, dry it, and then put some carbon fiber wrap on it to match the look of the car interior rather than looking like cheap rough-edged nylon.
Mostly it's because all of the car dock options so far that I've found have exposed wires, are ugly, don't provide charging, aren't engineered to sit nicely in a shelf, you have to plug in the phone seperately, and usually don't hold up to... spirited... bouts of acceleration. I'm pretty sure I can fix
all problems of these for not too much work... so I will
