Shelf used to sell my own honey (well the bees honey!) from home. Made some slight modifications to it - shortened the lugs on the brackets that go to the shelf section of the Hexagons so that the jars fitted on the shelf.
Top shelf printed in Hex pattern from Hex scad, rest of shelves 3mm thick squares of Acrylic.
Rather than screwing the brackets I glued them to the acrylic.
