Because apparently I’m a glutton for pain … Why, you ask? Because a) speed (LPD8806 vs. WS2812B) and b) cooler, diffused LEDs.
I will need a very compelling reason to actually make these though … at any size. 
(Even if I did, the dimensions will likely change by another 1 or 2mm.)
Because you can, what other possible reasons could there be?
Nice work. I’d throw in on a test run.
Hah, you and me both.

Have you considered sending this to your PCB guys yet?
Haven’t gotten any compelling reason to do that.
