I needed a way to support some larger plants growing on my Tower Garden, but I didn't want to shell out $60 for the official support structure. So I bought ten 3/8"x48" wooden dowels for $10 and designed this little guy to connect the dowels in each corner.
I cut the dowels into 7" pieces for the vertical bars and 19 1/2" pieces for the horizontal bars.
For each level of support, I used 4 vertical pieces, 4 horizontal pieces, and 4 of these corner connectors.
I just installed it, so I guess I'll have to wait and see how well it holds up and functions over time.
