Customizable Housing (for small circuits)

I needed a case for two [small circuits](http://www.dahlgrimm.de/Arduino/K8200/K8200-S3.html#Hotend_Luefter_Regelung) (see photo).
In order to make it reusable, I have adapted my design for the **Customizer**.

The inner dimensions and the wall thickness can be configured. Top and bottom are each half the height and will be connected via snap-in.
Openings must be added later (to the STL / before printing).

Both prints have already survived several snap-in / *snap-out* operations.

BTW: The parameter *Inner Width* refers to the outer wall - without the snap-in sockets.
If the width must be available on the entire height, the single wall thickness has to be added to the width.
