I didn't just post about it on social media, I actually exhibited it and participated in the event.
To be honest, I exhibited it just to get the pin badge... lol
It seems like it's pretty hard to even get into Gundam Base on weekends, so I took the highway after work on a weekday and went there.
I had no information about how or where the exhibit was set up, so I wandered around for a bit when I got there.
To be honest, when I found it, I thought it was quite small.
