I bought these "smart hexagonal panels" from Aliexpress

Then I noticed the holes for the connectors at the bottom. That's where these connectors came from.

It includes a 2-pin connector at the edge and a 3-pin connector in the center. Since more than one is usually needed, we provide 30 connectors for each model. It also includes a small tool that can be used to press the connectors into the holes.

When removing the connectors, you must be careful because they can easily break. If this happens

The SketchUp design files for these models are also included in the download!

In our case, I formed a double line made up of 31 hexagons. I used 29 USB connectors, 31 two-pin connectors, and 30 three-pin connectors. This ensured excellent stability, and the entire structure only needed to be connected at three points on the wall, namely the top-left corner, the top-right corner, and the top-middle part.
