I then assembled a complete 3D model with all the necessary components.With the 3D model complete, I could then design an enclosure to house the PCB and know exactly what it’s going to look like before printing it. I even incorporated a little cable strain relief.
There are no mounting holes on the PCB, so I can’t use board stands. I had to think of an ingenious way to secure the PCB into the enclosure, keeping both sides of the PCB visible, with a model that I can actually print
The solution was to incorporate some little raised rails along the inside of the enclosure. The PCB will be held in place by snapping it into the 3D-printed frame between the inner-divider and those rails.

I think it’s going to look pretty sweet. I don’t want to hide the PCB in a little project box where all you can see is the display. I want to showcase the PCB and the electronics.
