OK, sorry to repeat myself, but I made another iteration of the box design. This one looks better. The top is now glued on, and the side-walls are thin and fit outside the top. Well, it is best described by a picture. The design is on thingiverse.
Here’s another attempt of making a case for the MSP43o Launchpad, with room for the LCD board I’ve made and touch sensors. The black side is 3d-printed, while the top and bottom is laser-cut. In this model I’ve used screws to fasten the top and bottom plate, but it may have been prettier to glue the top plate on. I could have chosen a less transparent plexiglass/acrylic, but I did it this way in the prototype to show the inside. It would probably be nicer with a less transparent one, but I would have had to cut a hole for the LCD display. I wonder if I could maybe cut a square hole for the lcd display and cut a similar square in transparent plexi, and glue it inside the whole. I might try that out.
There is a room in the side for the USB contact.
There is space between the capacitive sensors on the board and the top plate, and it turns out that air is a bad material to ‘conduct capacitive touch’, while silicone apparently is pretty good. So I filled the room with transparent flexible silicone glue from a tube. The type you use on the bathroom to waterproof stuff. I had to turn up the sensitivity in the firmware, from 1000 with nothing there to 50 (so the effect on capacitance is still pretty big). The acrylic is about 1.5 mm thick, so the total is about 3-4 mm of silicone plus 1.5 mm of acrylic.

I’ve designed various versions of a Robot or Motor Driver boosterpack, but this is the first one I’ve actually produced the PCB for. This board features support for:
Here’s a picture of the board:

So every cool platform needs a laser cut acrylic box (apparently). I’ve now designed one for Launchpad, and here’s a picture.
The design is still a bit work-in-progress, but here are the files anyway. Expect some changes. The screws don’t quite fit for example, but I might change it so that the top is glued on, making the top slighly nicer looking with no screws.

Here’s a paper house I cut on my laser cutter. My kids built a few of them. The plans are here.
