Glass Tiles: Single Test Cell

A single glass tile rests on the ridge around the pyramidal interior:

The bottom has a cutout for the WS2812 PCB, with some in-the-model support for simplicity:

Which becomes this in real life:

There’s plenty of PETG hair inside the opening, which seems like a Bad Thing all around.

Cleaning out the worst of the fur, taping a WS2812 LED into the opening, and dropping a white-ish tile in place:

Obviously, JPG compression wasn’t built with a finely textured granular surface in mind:

But it looks really nice in a dim room!

With a physical object in hand, it’s obvious the pyramidal interior adds exactly zero value:

• Direct rays in the beam from the WS2812 don’t hit the walls
• Light outside the beam doesn’t contribute much after hitting those irregular walls

So the next pass should be just a hollow box with tweaked tile & PCB measurement: rapid prototyping in full effect!
