FlowTray Series – Artist 4 | Stackable Art Supply Organizer With Lids

Organize brushes, palettes and small paint tubes with the FlowTray Series – Artist 4.

The tray combines a long brush channel, a large palette compartment and two smaller compartments for paint tubes or other art supplies. The layout is designed for a compact painting workstation and remains compatible with the other trays in the FlowTray Series.

### Features

- Long channel for brushes and other painting tools.

- Large compartment for a removable palette or flat supplies.

- Two compartments for small paint tubes and accessories.

- Sloped retrieval surface in the brush channel.

- Rounded internal corners.

- Stackable with all organizer trays in the FlowTray Series.

- Single-piece design with no magnets or additional hardware required.

### Dimensions

- Overall size: 168 × 118 × 26 mm.

- Brush channel: 163.2 × 28 mm.

- Palette compartment: 108 × 82.8 mm.

- Two paint-tube compartments: 52.8 × 40.2 mm each.

- Nominal wall thickness: 2.4 mm.

- Nominal base thickness: 4.8 mm.

All dimensions are nominal. Rounded corners reduce the usable area for rectangular objects. Small tubes can be placed upright; compatibility with specific tube brands is not guaranteed. Long brushes may extend above the rim and prevent stacking. The Pen & Brush Cup fits into either paint-tube compartment as a loose insert.

### Stacking

The underside locates inside the rim of the tray below, allowing different FlowTray Series layouts to be combined in one stack.

Remove brushes, tubes, the cup and any other objects that extend above the stacking area before placing another tray on top. The trays are gravity-stacked and centered by their geometry; they do not use a snap-fit or locking mechanism.

### Suggested print settings

- Orientation: flat base on the build plate, compartments facing up.

- Nozzle: 0.4 mm.

- Layer height: 0.20 mm.

- Walls: 3 perimeters.

- Bottom layers: 5.

- Infill: 15–20%.

- Supports: designed to print without supports.

- Material: PLA is a suitable starting option for dry indoor storage.

These are suggested starting settings, not a tested print profile. Use the appropriate profile for your printer and filament, inspect the sliced preview and print at 100% scale to preserve stacking compatibility.

### Files and validation

STL, STEP and a geometry-only 3MF are provided together with the editable CAD source. The 3MF does not contain a configured printer profile.

The geometry has been digitally checked as a closed, single-part mesh. The STEP file was successfully re-imported and the 3MF geometry matches the STL.

The model has not yet been physically test-printed or slicer-tested. Actual fit depends on your printer, filament and print settings. All preview images are CAD renderings, not photographs of a printed model.

If you print it, please share a Make and let me know how the inserts and stacking fit work on your printer.
