This is a snap-shell for the Famicom Everdrive N8 with a hole for the optional, user-installed, USB port.
There's some information about installing the USB port on the Krikzz forum. The tools to use the USB port are linked from the edn8usb repository on GitHub.
The label used in the photos is a modified version of the labels available on this forum thread, and available with the OpenSCAD sources. The labels should be printed at about 9cm x 4.3cm in size.
