Customizable paint bottles holder with optional paint brushes storage

The simple holder to organize small bottles of model paint. I made it precisely to fit in a Tamiya Painter bottles. They are 24mm in size which should also accept other 10ml paint bottles. You can quickly adjust for any bottle size you need. Also, you can add a brush and misc items storage. You could generate any sizes grid, or you can download one of the sample files I've included.
