I received the remaining parts (bolts and electronics) just a few days ago, so I was able to finish up the machining and get a scanner mostly assembled. I should have the final assembly done sometime tomorrow, so I'll be able to finalize the "assembled scanner" price then.
Here's the updated prices:
Machined Parts only: $165
Complete kit Price: $180
Electronics kit only: $15
Assembled Scanner: $240
As for the LED diffuser cap, I didn't like the look of it and it really reduced the amount of light coming out of the scanner.
I also tried a plain piece of clear plastic in front of the LED, but that also reduced the amount of light and I really like the look of all those colors.
I think leaving the LED as is or a-natural, really gives the final product an illusion of "scanning" as if it's really doing something and that's really what we want after all.
