I wanted to bring the usb port to the front without having to do any major changes or buying any extra nuts or bolts.

unscrew the screen swap out a longer screw that comes with the minis spare parts. slot the new printed part into the screens hole and put the longer bolt through. then you can fit the panel usb extension cable.

Im afraid that I couldn't think of how to make it without supports so make sure you turn them on. 

you may need to trim the pin a bit to get it to fit properly because i found the supports didn't manage to stop it sagging completely

attached are the fusion 360 files!
