Coincident vertex in two separated meshes

Hi Daniel!

Thank you for your fast response! I’m sorry that I wasn’t specifying enough, I need all of the internal parts too. I have split the breps for clarification but unfortunately, it didn’t work out well and these are now open breps. Could you give an example on how to insert and fix the vertices?
I have attached the rhino file again.
Thanks a lot!
