I threw a video up here:
I printed this in white amazon basics PLA on a Prusa Mk2.5, all in one job.
Assembly was pretty frustrating. I found the clips to be too loose and they kept falling out on me, but added superglue on a bunch of the connectors/faces and it worked out. It's pretty solid once fully assembled.
I'm happy with how it came out, even though the diffusion would probably have been better if I'd followed the instructions about minimizing infill/shells.
Amazon Basics PLA
If I printed this again, I'd do it with fewer shells (this was 2) and less infill (this was 20%). While it works, I think it would pop better with less infill.
Lights are standard 12mm RGB pushthrough ws2811 pixels. Code running is just FastLED demoreel on an arduino nano.
