I am 3D printing a drone and I need very good tolerances for the holes so the arms and motors align correctly.

I have two sets of 4 holes for two solid objects (Imported as STEP)

I want to align the two objects perfectly and possibly by using constraints. I was already able to create new Parts from the two .step files and draw sketches where the holes are.

How can I do this in Freecad?
