Case designed for a Raspberry Pi2 + HiFiBerry Digi shield.
I use mine as a dedicated Musicbox -> http://www.pimusicbox.com/

You can also use the HDMI from the Pi, but I could not get a stable connection on my Denon amp.

The top of this case is compatible with the bottom of this one:

Which is based on this one:

In case you want to modify this design, you'll find the .stp file here;

4x M3 x 16mm to mount the Pi+HiFiBerry
print the 4 spacers to go between the Pi and the HifiBerry
4x M3 x 40mm + locknuts to close the case (assuming you use the wallframe/foot)
