Here is my version inspired by NanoLeaf.

There are 4 different thicknesses of hexagons to add dimension (25mm/30/35/40).

And a textured lid (remember to sand the seam on the hexagon and on the lid before assembling them together).

It works very well with colored filaments from the Meta range by Sunlu (except for the black one, of course).

There are 3 types of supports:

Round with 3 holes: placed at the ends (to raise the whole structure), Round without holes: to hold 3 hexagons together, U-shaped: to solidify the structure.

The pieces of LED strip are attached inside, at the end that will be near the wall.

Printing Instructions:

• Hexagon: no infill

• Lid: adaptive layers

or use 3mf files.
