Totally new to all this.. so follow at your own risk. :)  Printing the power box now, but was able to get the board flashed and things up and running.

Ran a test using a white PLA (top images, lights on/off) vs a "clear" PETg (bottom images, lights on/off).  The clear PETg doesn't glow as much as the plain white.

Also ran another test using metal tape as a backing inside the "bottom" piece.   Surprisingly, it didn't add all that much.

Did some testing raising the top panel which appears to help diffuse the light better.  Here is a comparison of my modified top panel vs the standard one.

Would love if someone could CAD the top panel properly, I simply stretched it in TinkerCAD.  It works fine as is though if anyone wants to use / test.

Making some good progress.   The 3 LEDs per corner and the thicker top plate seems to be providing the best results.  I haven't changed the bottom piece in these, i'm using the standard v2 file.

1st image is using 3 LEDs per corner and my new modified thicker top plate, next to panel with 1 LED per corner and the thicker top plate.

2nd image is using 3 LEDs per corner and the thicker top plate compared to 1 LED per corner and the standard v2 "thinner" top plate.

Lastly, completed the power box...

are you using the 60 LEDs /m strips or 100 LEDs/m strip? I was thinking of buying the 144 LED/s strip and seeing if I can fit more per corner would u think its possible?

I think it's the 60 LEDs, I ordered whatever was on the main page. :)  https://amzn.to/2Sr4q2V

Don't think you could get anymore than three in the corner.  They are already starting to bend around the edges.

I  just bought the 100 LEDs/m gonna see how that goes anyway.

Two panels completed.  Left the top of one open so you could see inside.

Added some layers to the corners of the top panel to try and block out some of the light.   The light still bleeds through and I don't like how I can see the layer lines.  You can also see the infill.   Going back to the standard taller top.

How thick is your new top plate?

I stretched it to be the same height at the power box.  I dunno the actual dimensions.  The little pins on each corner are a little larger but it works fine. I think I attached the STL in this thread.

EDIT:  Attached STL

5 panels completed.  Using the taller top panel.  Ordered another strip of LEDs and connectors.

Attached to the wall using 3M command strips.  They are a little thick, but work OK and allow me to remove them via velcro.

I attempted to add a 220 OHM resistor, but it must be the wrong size as it messed with the signal, the lights would flicker.  I did add a capacity though, which seems to be working fine.

I remodeled the top part to be 5mm taller , also a bit thicker on the side where it needs to if you use T shapes to hold the triangles together , it is deff better for diffusing the light and you can only see the bottom pyramid if you try to. The little pins are where they are supposed to be so fits perfectly on the bottom part . Im also thinking of remodeling the bottom part to use smaller connectors and cables but would have to try out if the cable will manage the current before remodeling to fit it , the main idea is lowering the bottom pyramid as much as possible but will try when I have some free time.

P.S. I will attach the stl file for the top part I made , and a few pics of it even if the focus isnt great and they dont do it justice

Agreed, moving the top farther away from the light source helps a lot.   Iím also using three leds per corner which brightens things up considerably. I didnít want to go any thicker than the power box  though. Felt it started to get a little too bulky .   Would def be interested in a redesigned bottom which would allow us to use a thinner top with the same diffusion though.  Was thinking about smaller connectors also, didnít find anything quickly.  Will keep an eye for your updates.  Tnx.
