I just imported the 2 stls in blender
put them together, like in the same place as you wanted
Selected both as seen in the image, then File -> export -> STL. Make sure you have “selection only”.
Export it, open it in your favorite slicer, and that should work.
Blender can do a lot, I use it to design and modify a lot of things from thingiverse too, and I have learned a lot of tricks on blender too.
I also want to learn freecad to do stuff from scratch, but in the meantime blender does what I need.
EDIT: Most probably I did not understand the requirement correctly, is this supposed to have a hole? hit me up if you want, happy to help https://discord.com/users/poringo#6290
Does something like this works for you?
