Modular Paint Rack

thingiverse

I originally created a compact version to fit on my small printer, but as I added slots and tabs for assembly, I realized modifying it further made it far more versatile. Although I didn't include corner designs, this design can be easily expanded in both vertical and horizontal directions. For my own build, I began expanding vertically and then shifted gears, expanding horizontally as shown in one of my photos. This design has a capacity that's any multiple of 6, with each column holding three units wide and featuring one section with two shelves.
