How to make the B holes 3D??

I’m working on this merch design for my band and I’m very, very new to Illustrator. I would like to give the B some holes (B holes, ha!) but every attempt I’ve made to make the 3D perspective match the rest of the letters has failed.

For instance, if I try to erase a hole in the B once it’s already been 3Dified, it just messes up the whole thing. If I add holes to the B and then make it 3D, the shadow is not on the right side, plus I need the white of the hole to be transparent, like the white of the star.

Surely there is a way, I just don’t even know where to begin. I’d be happy to provide more steps of what I’ve tried if necessary, just didn’t wanna crowd this post.
