An 8 year old tinkerer from Canada build a few of our GBCs including the GBC 58 Dump N Drop and GBC 47 Mill Madness and combined them in one loop! His father send us an a video showcasing the whole operation. He also mentioned the following:

Thank you for this wonderful GBC module and free building instructions.
One of the greatest holiday gift for my child ever.
Dump n’ Drop is small module yet gave them lots of fun and exciting challenges, ways to be more confident, and there is always new discovery in every time!

My 8 years old said they love Dump n’ Drop especially because it is compact so they can carry it to anywhere and easily attach to other modules. I am sharing a video recorded between December 2024 and March 2025, as my child would like to show how they connected GBC 58 Dump n’ Drop with other modules.

And grately appreciated that this GBC can be made from the existing LEGO kit currently available!

Thank you for the nice words and video.

That you can control your beloved Power Functions Servo motor with Buwizz while still using the 2 PF Buwizz motors? Normally you would be of 1 PF port short. But with our Powered Up to Power Functions Adapter you can control all 3 independently! Awesome.
WW Bricks Studio made a nice video demonstrating this with the use of our adapter cable.
