An accessory box in the shape of the Nintendo Switch logo, it could be used for storing cables, headphones, joycon accessories or anyhting else that you can get to fit. (you could scale it in X,Y or Z's to get different shapes and sizes).
The circles are optional and can be added.. or not, and there is a lip on one side of the joiner which will locate into a groove in the right body to keep it secure.
Parts shown were printed on a Robox and the pictures were taken with a potato :/
Hope you like it!
