Raspberry Pi case with breadboard

I needed to extend the control of my 3D printer with LED that I could turn on and off remotely. For this I found a nice guide here: https://dordnung.de/raspberrypi-ledstrip/
After I connected all the components, I wanted to put the Raspberry Pi with the breadboard to setup my light control in a nice compact box, next to my printer (and away from my curious cats).
So I extended a simple Raspberry Pi enclosure with a placement for a breadboard. I kept de top lid much open to give room for cables and the Mosfets i needed.
As my 3Dprinter (Snapmaker 1.0) has a maximum printsize of 150mmx150mm i needed some adjustments to design this casing within these constrains.
This is my first step into practical 3D design. Any feedback is welcome.
