You can see a great example of this HEX Panels on Engineericly 's YouTube Channel.

I printed mine with 100% size (you see it on the pictures), but next time I would rather use 120% or more, because it makes threading the LEDs easier and bigger things fit into the shelves.

What you need:

LED-Strip (if you want different colors on each cell, use an RGBIC LED Stripe)
Printed Cells in a non-translucent Material
A translucent material for the windows
some clear material for the (Shelf-Lightcap's)

Materials & Colors:

Print the Panels, color and material doesn't matter
Print the Panel-windows in a translucent white,
(or in your desired color when you are going to use a simple white Light strip)
Print the Shelf-lightcaps with a transparent or highly translucent Material

Installation:

If you use the reflectors, mount them first.
Arrange the cells like you want it on the wall
Fix them together with clip's and glue.
Make a simple drawing how to manage the LED Stripe.
Fit the LEDs inside (this can be a little annoying)
Add the Light caps on the Shelf.
You should fix at least the cable with some hotglue or somehow else
Put it on a wall
Fit the Windows and enjoy :)

Optional parts:

Holecap - to close the holes on the side.
Light cap - only needed for the shelf, looks like a integrated lightbulb (clear material).
Clip - use them to fix the panels together.
diffuser- print it with clear material
Reflector - if you print the cases in dark colors you should use the reflectors, you will have a much better looking light distribution.

If you have trouble getting an even light, you can print the thicker (diffuser) windows or use the LED diffuser (clear petg/pla). If that doesn't help, fill the inside with clear/white silicone (like this) or cotton wool.

Here you can see how to wire and control your LEDs with an ESP32 in general:
