The columns (slightly transparent on the 3D render is made by stacking disks cut in the same acrylic than the rest and screwed together). The only glue involved in that is the one that glue the metallic name-plate on the wood. If I had to do it again, I think I would laser engrave the wood so the name plate gets inside it and use a more shiny acrylic (if that exist).
The device looked way nicer than on the pictures, I found some pictures of them before the name plates were added.
