This is a hexagon wall light. It can be designed individually as the individual hexagons are plugged together with a connector.

An ordinary LED strip can be used as a light source. Very nice projects can also be implemented with WLED. You can enter WLED as a keyword on YouTube.

Here you can find an example (The video is not in front of me and only serves as an example)

If someone prints it, I would be happy to see photos of your projects in the comments
