Dropper Bottle Flat Rack

This is a modular flat rack that I made to organize my model paints in a file cabinet drawer. Each slot can fit any major brand of 15mL dropper bottle, upright or inverted, including Reaper, Vallejo and Army Painter. Each slot's footprint is 25mm or about 1inch. I've included racks at 6x6, 3x6, 2x6, 1x6, 3x3, 2x3, 1x3, 2x2 and also a 1x1 if you'd like to customize a configuration in your own slicer.
