Nothing beats a semi-gloss black finish. All the 3D-printed parts are also supposed to be black when I start production but I had a lot of white filament that had to suffice for the prototype. 

Also I am awaiting a shipment of nice black screws for the finished kits, the plated ones on the prototype are just stuff I had laying around.

As you can see I have also fitted the first CNC-cut sides in black plastic, and also painted the top aluminium cover. 

The firmware is also coming along steady so hopefully I can present you with a demonstration video within a week.
