Got tired of dropping those little magnets for the Gridfinity accessories. You can glue a 6mm magnet in each end (be sure you get the polarity correct). Then separate and lay the magnets out on the table. Grab the tool with the appropriate end towards the magnets. if you approach the magnet from the side it will jump to the end of the tool. You can then press it into the Gridfinity accessory and slide it to the side. The magnet will stay in place. Use one end for the base grids and the other for the bin bottoms.
