Deco Shelf Support

Simple support for AR-Shelving's Deco shelving system - I found the original somewhat lacking when shelves are loaded with extra weight (ie, my 3d printer). The supports have a ridge at the bottom that slots into the grooves of the Deco support tubing. Each support needs 2x M4x20 bolt (cylindrical, allen key head) and 2x M4 nut (may be hard to press these in - just use a bolt to draw the nut into its socket) Do not overtighten! Suggest 100% full throughout or at least in the "business ends" of the supports.
