This is a case for the JamBox that was part of HackerBox #0028.

You need to print 8 buttons, and one each of the other parts. To assemble, hold the lid upside down and insert the buttons into the holes. Insert the JamBox into the bottom part of the case (it only fits one way). Hold that assembly together by pinching the board against the case using the breadboard section. Turning it upside down, fit it over the lid and carefully guide the clips into place.

NOTE: This is a new clip system I'm experimenting with, and I think it works very well. The downside to it is it's very difficult (but not impossible) to disassemble the case without breaking clips.
