I love this paint organizer by Artist11d, and it works exceptionally well for all my miniature paints. I wished it was taller as the space I have for my colors will allow more shelves to be stacked vertically. I added some extensions that will enable the builder to assemble more than six shelves in a module. I was able to add extensions to allow twelve shelves in a module that holds 60 bottles of paint. Additionally, I've created additional shelves for 3, 4, and 6 bottles.
