The wine rack is made up of three sets of supports. One set (11 - 17) is vertical, a second set (18 -25) slopes diagonally in one direction, while the third set (26 - 33) slopes in the opposite direction. Three supports, one from each set, are connected by bolts (35) where they cross, forming triangular shelves (44) for the wine bottles.
