This is a photo of a computer screen with a program for designing 3D objects open. The edited object looks like a coin labeled "GTG."

A 3D printer (Prusa MK4s) can be seen in the Fab Lab of the Berlin Museum of Technology.

The finished GTG coin is shown. It is dark gray.

✨Last day of the #gtg2025 annual conference at the #Technikmuseum Berlin.

During the #FabLab tour with curator NoraThorade, we got 👋hands-on and created real value! 💡🛠️
