Help with a Boolean action

I am trying to boolean-union parts 2 and 6 but I am having problems with the operation. I guess the system is trying to tell me where the problem is with a red dot, but I don't get it.
Here is the link to the document https://cad.onshape.com/documents/47511328b3f45c005147b11f/w/a23fa639338db56b28b0e3b0/e/c7854ba440ba1757d3cb6cab?renderMode=0&uiState=689616068875be0cf0d7089d.

It's something called a non-manifold condition and is common across most CAD systems. The way to overcome this is often moving the common intersecting vertex point a small little bit and then it should boolean together. I'll give it a try and share the document.
You can move face on the green part where the red dot is. then boolean then delete faces that aren't needed. That's the short answer. the long answer is to go back in time before attempting the green part at all and maybe use variable fillet or learn surface modeling

Variable fillet example.
I need to learn surface modelling. I have been missing that since I started working with OnShape. Thanks for your comments and lead.
Thanks a lot for your help.
This seems to be a very simple solution also. I was not able to obtain a result with variable fillet, but your example and a little reading of the documentation will help a lot.
variable fillets can be tricky. Starting small and increasing size incrementally can aid in visualization of what the software is trying to do and why it’s failing to create the fillet. I wish I had a specific tutorial to point you towards. I just picked up most of it by trial error and clicking on everything to see what makes it tick.
I wouldn’t say surface modeling is missing from the beginning. It’s something to iterate into your skillset at some point for sure though.
