I uploaded camCaseMk1.zip as an example of prototyping progress. The alignment features between the sandwich pieces for the board didn't print well (waaaaay too small, need to make these better), the top cover has no way of locking in place, and the ear clip is both incredibly too large and not adjustable. It would be replaceable if the slide-in features worked, but those also didn't come out well, so they require redesign. One step at a time is how you get down the stairs :P I have a pretty good idea for the alignment features, so that'll probably be the first thing fixed for Mk2.
