This is a new enclosure for original Bambulab Smart Accessory Control Box project, so all credit to WolfWithSword for the work to actually figure all this out!
It has a locking power connector, embedded magnets, and flush mount barrel jacks.
You can find a more detailed breakdown of the changes and BOM on my site.
