The last parts are almost finished. The sides and top cover will be made of CNC-cut ABS plastic sheets that should arrive from the manufacturer on monday. Since my own CNC mill broke down I had to find a local producer instead, but that will pay off anyways when I scale up from a handful to perhaps a hundred kits in each run. 

The top cover then needs to be thermoformed in a U-sized shape. That is why I'm making a mold right now, on which I can drape the heated plastic. Just put the sheet in an oven for a few minutes, take it out and bend it around the mold. I'll try to hold it in place with two straps as you can se in the pic. Will it work? Time will tell.
