"Pictures are not renders but the actual finished prototype. Legs end with an M-39 rod that screws directly into the corners of the table with the tapped thread. Hand tight is enough to provide stability and there is no tools needed for assembly.Smaller holes are there to insert stacking rubber inserts.All machining marks get removed during the anodizing process. Different aluminum alloys result in slight color variation. Legs and top are not on the same plane. Light bouncing differently results in almost impossible to appreciate color variation. "
