About this 3D model

These are some dropper bottle paint racks I made up for my collection of paints at home. They can be stacked on to of one another on the wall and glued together. I used 3m tape between them and the wall to stick it in place and it holds great.Fits:Army PainterGame ColorModel ColorTurbo Dork(but its a really tight fit for only the bottom of the bottle)And similar sized dropper bottles.
