So here is my Raspberry Pi Wallmount. Perfect for your smart home projects, with plenty of space inside for other controllers ,relais, or whatever you want. You can also attach a standard 30x30x10 fan. All you need to buy are 4 countersunk M4 bolts and 4 M4 nuts, and screws to attach the display and raspberry.
(Designed for the raspberry pi 3)
If you have any ideas or recommondations for version 2, please write a comment
Have fun printing it!
UPDATE 30.10.2016: The 4 holes for the display in the front piece weren't quite right(2,5mm off) i've corrected this
