K8200 controller box

I designed this box two Years ago for the controller of my K8200 3D-Printer. It can be mounted to the aluminum frame with M5 screws and its cover includes a cooling fan as well as space for a cheap step-down converter. This is used for fan speed control (maybe a little bit oversized but I has this converter already in my lab).
The prints on my images are early ones and not from best quality. Nevertheless the box is doing good job and the models may be useful for other K8200 users as well.
Note: Special screws for plastic are used for mounting controller and box covers.
