A dock I received was missing it's flap off the front where the HDMI and power cable goes.
Couldn't find one on the internet to print
So I decided to try have a go myself, it's untested currently as print time is about 3-5 hours, depending on orientation for supports

Now fits perfectly, i'd say to print it flat with supports but this ups the print time a lot and uses a lot more filament, it does print standing up but you lose some of the Nintendo logo
