Diego Baca strikes back! His epic GBC Tower 2 is from far the biggest LEGO Great Ball Contraption around worldwide. After his first huge GBC Tower, issued in 2019, we thought he couldn’t do taller. We were definitely wrong: his LEGO Tower II is a more than 2-meters-high mind-blowing gigantic beast which required more than 45500 LEGO bricks to be built ! (i.e. 3 times more than the previous tower…). Diego pilled several GBC modules together to create this titan Lego marble run machine, that he sees as a tribute to Akiyuki and to all the GBC builders in the world. Not only he did this huge build but also produced high-quality (available for free on his website!) building instructions for whoever is brave enough to reproduce his massive masterpiece. If you don’t suffer from vertigo, if your living room has a high enough ceiling and if you have a large budget to spend on LEGOs, don’t hesitate to start building this quite unique construction!
