I would have liked XT-30 or XT-60 connectors, but the footprint of panel-mounts is enormous, and it’s also unshrouded pins on that side.
For the 12V, I’m adding a step-down converter. The ones I found with a small enough footprint don’t have mounting holes, so I experimented quite a lot with how to fasten it to the bottom plate.
I opted for a TPU clip-on holder that I can fix to the case with glue or double-sided tape. I hope it allows me to get the PCB in and out even when glued. 4/
I have to add that any advice is welcome. It’s my first 3D printing project, so I don’t know how it will turn out.
I’m probably over-engineering the TPU holder, but it seems safer than built-in clips made of PLA, or whatever filament I will use to print the case, because I can test different sizes, and it’s less likely to break if I make it too thin.
By the way, which material do you recommend? I’ll be printing at my local maker space, so I have options. 5/
