This dock mounts all of your Nintendo Switch controller accessories to the back of the Switch Dock itself. It locks itself in when the back cover is closed. The accessories slide easily on and off. Make sure the sliding rails are sanded smooth, or the Joy-Con trigger extensions could get caught on the rough layer lines, making it extremely difficult to remove from the dock.
There is a slight angle along the top to allow a snug fit inside the Nintendo Switch Dock. This means that when printing upside down, I usually leave supports on just so that there will be a layer or two protecting that slight angle. You could probably print this without supports on, but I haven't tried it yet.
