Every Christmas break is another opportunity to go down to Adafruit Industries in NY, NY and (in addition to having a good time) exercise my nascent industrial design impulses. The new tradition is to knock out a kit enclosure. Adafruit's design constraints were as follows:
1. The enclosure needed to be made out of 1/8" acrylic.
2. It would preferably be completely enclosed.
3. She didn't want "just a box."
4. It should have a variable tilt angle to accommodate the viewing angle of the LCD screen.
Until I get a copy of my notes back (which show my entire thought process, including doodles and the Bad Ideas Club) - these photos will have to suffice. I designed everything to slot together because I really like slotted flat-designs (go read Nomadic Furniture 1 & Nomadic Furniture 2 for more fun flat designs and examples of things Frank Gehry was actually good at designing -- PROTIP: It's not buildings)!

There were a couple of things about my prototype that I knew Adafruit didn't like. I had an asymmetric profile shape - chosen because I based the design off of an isosceles triangle, and a truncated triangular side profile meant I could slot the top piece in for ultimate interlocking action. I also really enjoyed the idea of having a low, flat very Byzantine/monolithic/robots-will-eat-you shape, which made the enclosure larger than Adafruit's prefs. She ended up removing the top and changing it out to match the tab-locking bottom piece, while retaining the slot-locking sides and front piece, which allowed her to shrink the front piece down and make the area surrounding the LCD symmetric. The final case retains a lot of the details I enjoyed making while matching Adafruit's own preferences. The following pictures show what the final production design will look like.
