Can you explain this sentence that you stated as I am a bit lost what it means
Note: The L_shape.stl is to join the first table from floor and the second together. Rods of plastic are here to center the L without mesuring, cut them when you found their good place :)
Where does this L bracket sit because all of the braces made screw to the top of the first table and the legs of the second table. What are the Rods of plastic you are on about also?
