fdcanusb enclosure

To get ready for initial limited production of the fdcanusb I wanted to make some kind of enclosure so that you didn’t have to just grab the raw PCB and risk ESD failures.  I also wanted to be able to expose the status LEDs without having to do a window or anything else with multiple materials.

So for now, I just used a translucent PETG print, with light pipes and a thin wall above each of the LEDs.  The result isn’t too bad, you can clearly see the status LEDs and it feels plenty rugged for desk work.
