Paint Bottle Holder Customizable

I got about 30 bottles of these paint. I want to put them in tidy, easy to pick up and recognise the color. That's why I make them to be slanted.

It is a Customizer so that I could print them as I could easily manage the pattern and numbers of bottles in total. You could setup the whole container with row, column or even the slope.

I hope it is useful to you too. Welcome any comment or modification ^^
