I whipped up some end panels using Inkscape and sent off to Ponoko for fab. I chose 1.5mm thick black acrylic. Black wasn't my first choice, but Ponoko didn't have many options in acrylic less than 3mm thick. The nice, cheap, extruded enclosures from Adafruit didn't come with dimensioned drawings, so it was a bit of guesswork to get the panel overall size and mounting features, but after a few iterations with paper printouts, I managed.

I used crayon as the infill on the panels to allow the engraved text to show up. My teenaged son referred to it as "ghetto". I call it "industrious".

Now, just need to wait until next January to unveil the DerbyLink to the "pit crew"...
