Wrench Holder - Magnetic

I created large and small wrench holders to organize a drawer in my toolbox. I've recessed holes in the bottom of these designs to accommodate 8 mm x 3 mm round magnets to keep these holders in place against the metal of the toolbox drawer. I plan to put drawer liners in the drawers in the future so I glued the magnets on the bottom of these holders instead of in the recessed opening, and I will cut small holes in the liner to allow the magnets to reach the metal surface. The magnet height and drawer liner height are almost identical.
