First, the connectors that came with my cubes are a pain to use, so how many cable ties does it take per connection to be stable? Second, is it better to put the coroplast box inside or outside of the grids? Third, is it okay for it to overhang the table a little bit? Fourth, do I have to put in the upper level right at the initial building or can I wait until I've had it all set up for a week or two to add it? Fifth, how the heck do I cut the coroplast to make an L-shaped cage [I have two sheets of it]? Sixth, anything else I should know before beginning?
