This is a cleat system for the Tanos T-loc Systainer line of toolboxes that makes it possible to attach these 3d printed parts to a worktop and attach the worktop to the Systainer T-loc line of toolboxes. Parts shown mounted on an mdf-top and that is in turn mounted on a festool systainer stack. Print 1 of each and fasten with woodscrews.
