Just the back-side of the 3xCAN box this time showing holes for Ethernet, SD-Card, USB and Power. The power connector is not 100% yet as I lack components. Getting a 3D printed panel adapted is a lot of try & fail, but I got it right in the end.

The left side have room for the 6th (and 7th) DSUB-9 connector + I need to consider where to take out some leds to indicate status on the content. This back side will be used on a lot of modules. I am throwing the word “module” around a lot, but we have the entire box as a module and we can hav sub-modules inside each box as well.
