That enclosure looks awesome. I love the screen too. I thought about scribble strips, but in practice I find I don’t change layouts that often and get used to where things are, so I just use a label machine.
I have the enclosures manufactured from my CAD designs at a local machine shop. The one pictured is from 3mm aluminum sheet of which I have 5 left. I will need a new enclosure design to better match the new PCB as there are many unused holes on the back side now.
