ANET A8 | Power Supply Cover - Power and Switch with USB power
thingiverse
I really liked the design on the original but wanted to add a DC-DC 12v -> 5v USB converter to power my Octopi from the same PSU. This one allowed the space to add the converter and space to set a cut-out for the USB port. I used the following converter and switch for this: Converter - http://www.ebay.co.uk/itm/201730635313 Socket/switch - http://www.ebay.co.uk/itm/222413951444 I added a rim on the inside corner to fit the converter - you will need to snip off one of the mounting tabs on the converter for it to fit in. Mine is just held in by friction, but I guess you could add a dab of hot glue.
