After searching a while, and wasting a lot of filament trying to find an organization system for my acrylic paints, and not finding anything I liked, I decided to design my own. My requirements were it had to:

1. Hold 2 oz. bottles of paint
2. Allow a slight angle for the bottles
3. Have space below the opening for a label
4. Be stackable
5. Be expandable
6. Have the ability to be hung from the wall

What we have here is the base for that system. The tabs on the ends are alignment tabs for stacking. They can be left loose or glued for more stability. I'll also be posting a center section and a top section. Hope you can benefit from it as well.
