Huge LEGO Ball Machine Tower – 45,000 Pieces & 20 Motors!

Thanks to @Diego Baca for allowing us to share his amazing LEGO great ball contraption tower!

The tower uses eight Akiyuki modules distributed vertically across two parallel 7-foot structural frames. The tower also uses several additional modules and techniques from many GBC builders from across the globe – an homage to the creativity of the GBC community. The result is a giant MOC with more than 45,000 LEGO bricks!
