Will you have enough LEGO parts, time and space in your playroom to reproduce this gigantic GBC module? It’s not sure, because Diego Baca’s amazing GBC Tower module is, to my knowledge, the biggest and largest Great Ball Contraption module ever built! This epic building, measuring more than 6 feet high and consisting of more than 14,500 LEGO parts, is a vibrant tribute to Akiyuki’s GBC constructions. But instead of chaining the modules on a horizontal plane, this giant tower stacks them vertically. Diego Baca has done a titanic job here to ensure that the modules flow smoothly, but also by creating the building instructions and 3D modeling of this dizzying construction (available entirely free of charge on his site). One can only remain admiring in front of such an architectural masterpiece, not to be missed under any circumstances.

Tried to upload the stud.io file to a BrickLink wanted list. Gives an error part 755 does not exist. Anyone else have this problem?
Hi,
I wanted to try to see how long this would take to build and what type of pieces this has. I saw that the file are LDRaw and io. I don’t know how to open these files and I was wondering if there was a pdf form of this. Please let me know.
Thank you
Ajay
hello Ajay, the .io file can be opened with the free software Stud.io from Bricklink: https://www.bricklink.com/v3/studio/download.page
From this software, you can have step by step building instructions
good luck with the build
Thank you!
