Clamp for 8mm Rods

I designed those clamps to mount a newspaper basket ("Blomus 68477 Wires Newspaper Collector") consisting of 8mm chrome-plated rods to an old chopping board with wheels. I wasn't reading the newspaper on paper anymore and the chopping board would have gone to the trash anyhow. Now I up-cycled the objects into a basket on steroids err... wheels, to be used in the apartment or in the workshop.
