Hi, I'm new to this and am trying to figure out how to make use of the connectors in the menu. These are small components that need to be placed accurately to work but I can't find any videos showing their use and they seem to be clunky to move, orient and place accurately. If there is a tutorial on their use I would appreciate a link. I just want to be able to connect a few parts that can't be printed as one. A simple example would be a flat slab with a vertical slab at each end connected so as to make a simple table/stool shape.
