How could I get a similar effect like in MW19's gunsmith?

Hello guys, so I’m working on a gunsmith with UI inspired by MW19, and I was wondering how I could get the floating buttons to gather around the gun model.

Here are two images, what I have right now, and what I’d like to achieve:

I have a general idea how to offset the Billboard GUI, but I am not too good at math and have a hard time figuring out the general math formula to get the buttons to gather around the gun’s center like that, could anyone lend a hand?

Thank you!
