If you look at the photos of the face plate there are two holes for LEDs. One for power and one for AM indication. A while back I had made a pretty cool RGB LED color cube, using WS2812B LEDS. I had printed out a box on my homemade deltabot using clear PLA and it worked out pretty good. So the thought was to do the same thing for the LED diffusers.

I hadn't used the deltabot for while, so it took a day or two to get it dialed back in. But it is working great now. Below is an older photo of my bench at home, you can see the Delta in the foreground. To the right you can also see my PrinterBot Simple that I used to make the Delta.

It also took me a little bit to re-learn sketch up. Great program, but the learning curve can take a while til you figure out the best way to do things. I ended up drawing profiles and then using the follow me tool to spin it around a circle.

Quick hint I learned. Sketch up has trouble with "follow me" and features smaller than 1mm. So when I first drew them, I had done it scale and had some trouble with missing surfaces. I simply scaled the whole drawing up by 10x, did the "follow me" then scaled back by 0.1 and all was good. I printed them out with a shell thickness of 2mm and 40% infill. They ended up looking and fitting great.

I now need to cut a square hole in the side of the box to accommodate the USB Female B connector. I am going to connect a usb to serial converter and then use it both power and program the clock.
