Car Dock for Sony Xperia Z3

I was getting tired of those wobbly cell phone holders, so I made this dock. I included the STEP files, if you want to modify this for your phone.
It is really specific for the Sony Xperia Z3, and with my phone cover on as well, so really specific... (maybe works with other Xperia, not sure). It takes advantage of the magnetic charging port. So you drop the phone in, and it starts charging right away, because it lands on a magnetic charging wire. With Tasker I made it so that when the phone is connected to my car's bluetooth system, and it is plugged in, the car app starts (shown is Car Dashdroid, awesome app by the way!)
If you dont want to charge, you press the "eject button" on the top, which just lift the phone up above the magnetic charger. Also makes it a bit easier to get the phone out.
The big step on the back makes the phone sit lower, in front of the dash, which does not block the view at all.
If you want the charging to work, you will need to buy a magnetic charging cable like this one: https://www.amazon.ca/Magnetic-Performance-Charging-indicator-Compact/dp/B015WIV7O2/ref=sr_1_7?ie=UTF8&qid=1480384154&sr=8-7&keywords=xperia+z3+magnetic+charger
