Toyota/Lexus 3 Button Remote Key Case/Shell

Dad recently noticed that the plastic of both of the keys for his car had cracked, and asked if I could print a replacement. "Sure, people have already made these, I've seen it"
Well, there were some great designs on here that almost did the trick, but I had to make a few adjustments to make it work with Dad's car. The Panic and unlock buttons are symmetrical, so adding that hole was easy. I had to shorten the case and let the metal key stick out a further 1.5mm. This almost certainly makes the case weaker, but otherwise the key could not push far enough into the ignition lock when turning the car off which made it very difficult to remove from the car.
