About this 3D model
This is an organizer for Nintendo Switch Joycon controller accessories that clips onto the rear access cover of the Switch charging dock. The accessories slide in from the top. The 'backpack' is attached by opening the access cover of the docking station and clipping over the lip, and closing the cover. I printed this on a Toybox3D printer and quite happy with it. I used the default quality settings. The backpack is printed upside down to eliminate the need for supports.
