It has never been easier to add cool sounds and tunes to your Great Ball Contraption (GBC)! This GBC is entirely built using only parts from the LEGO Bucket Wheel Excavator and can be referred to as model C of the 42055. This GBC makes sure you master the GBC building techniques and tricks so that you eventually also can build your own GBCs.
Discover your inner Beethoven
Add cool sounds and tunes to your GBCs by adding our Xylophone Keys into the loop. The GBC 35 Musical Stairs Module features a nice tilted staircase with attached Xylophone Keys. These create nice clean tunes if GBC Balls roll over it or when hit by a GBC Ball. By building our GBC 35 you have a great start with GBCs and music by learning how to implement our Xylophone Keys into your designs.
Note that GBC 35 is a minimal structure just to hold the Xylophone Keys in place. It is required to implement and adjust the module yourself into your own existing GBCs. Let the creativity burst free :)
