I designed a little 3d-printed case for the Hifiberry DAC+ ADC Pro with a Raspberry Pi 4. Should also fit the non-pro version. Easy to print and assembles with just the nylon spacers and screws that came with the hifiberry. Should provide a basic level of airflow, and I think it looks ok. Designed in OpenSCAD, so changing the holes to fit other hifiberries should be really simple.

Also an easy to open version with a hinge is available at thingiverse. Might be useful in case you need to switch jumpers often.

  Thanks for the blog entry!
  Here a sneak preview of an upcoming version with two balanced XLR/Jack combo-inputs, and a couple of more small improvements. This is still awaiting a print of the lid, and my really bad soldering skills for the second connector, but looks like this is going to work well. If it does work well, I will share it on thingiverse soon.

  And done! The model with two XLR/Jack combo plugs has been added on thingiverse on https://www.thingiverse.com/thing:4753525 , with instructions.

  It's a bit less sturdy than the smaller one, but should be ok for most uses.
  
  If I connect a microphone on input 1, and nothing on input 2, and put the gain high enough for a dynamic microphone, there's quite a bit of hum on input 2. It mostly disappears if I touch the metal part of the XLR plug and something metal or the microphone at the same time, and becomes worse if I just touch the case or the 'push' button on the empty connector.
  Not a big problem, because I can just deselect that input if I use only one.
  I did not solder the ground/chassis pin on the XLR-plug, but of course did connect pins 1,2,3, T,R and S. Should I have connected that to something?
