The link is not called "Build your own particle detector physical facsimile out of LEGO", its called "Build Your Own Particle Detector".
Considering the general HN content, I assumed that a "model" LHC particle detector would be a scaled down version of the actual system, as in one that works, albeit likely at much lower energies. It's not like garage particle stuff isn't a thing. People build fusion reactors in their garage pretty regularly[1].
A LEGO model is very different from a practical model.
I confess I too clicked the link expecting some cool DIY particle physics stuff, and came away highly disappointed.
