Different heavy duty shelving feet (3 versions!)

Feet for heavy-duty shelves - a simple design with some practical defaults. I had three different shelf versions from various brands at home, so I made custom feet for all three.

There are three variants, each with a matching connector for placing them in a row, plus a shorter top piece that fits perfectly on top.

Variant 1 (Plate 1, 2, 3 and 4)

Variant 2 (Plate 5, 6, 7 and 8)

Variant 3 (Plate 9, 10, 11 and 12)
