Raspberry Pi Armor Case Extension with fast attach wall mount

The Raspi3 and 4 really need cooling, and passive cooling is enough with the massive Armor Case housing wich you can get between 10 to 14 Bucks (thermal pads and screws included). Just google "Armour Case Raspberry Pi". There are specific models for the different Raspberries. Wifi still works.

But: if you want to have, let's say a realtime clock in your housing (or other tiny things connected with the GPIO), the Armor Case needs an extension (see remix source for the first try).
And here it is! And it comes with a fast attachment wallmount to slide in.
You have free access to the sd card (to mention the most significant difference between the two case extensions.)

The Case extension should be scaled to 101% in X and Y (in height 100%). The wallmount is drawn a little bigger, should work with 100%.
If the walllmount needs to much force to slide in, just slide it in with careful violence (support areas needs to get smoothed a bit, than place it onto your Heatbed for a couple
