GBC 51 Gravel Works – Master builder access

Build without knowing exactly how it is going to function? This is only for true master builders we believe.
The building instructions are now already available and until we have launched the official product video of our new GBC 51 Gravel Works (42131 alternate build) this challenge is a fact. Who will be the first to send us their fan build of the machine in action? Looking forward already to these moments.

And here you can upload your fan build of it ;) We would really like that!
