A workflow that makes sense

From messy space to finished print.

Modularity guides the decisions in the same order you naturally make them.

Measure

Enter the width, depth, and usable height of the space you want to organize.

Arrange

Drag across the layout and turn connected cells into fitted trays, dividers, or solid spacers.

Personalize

Overlay a photo, freely place dividers, or scan an object to create its fitted pocket.

Print

Preview the complete layout, then export print-ready STL files for your build plate.

An interactive look

See the 3D viewer in action.

Drag to orbit, scroll to zoom, or use the view controls to inspect the complete example layout.

More than a tray generator

Design the whole space, not one box at a time.

Modularity brings the scattered steps of custom organization into one approachable workspace. The result is a layout that feels intentional before anything reaches the printer.

Complete-layout planning

Design the space as one coordinated system instead of generating isolated boxes one at a time.

Real-object pockets

Photograph an object on paper, extract its outline, and position the pocket inside an automatically sized tray.

Dividers where you want them

Use adaptable presets or place vertical, horizontal, diagonal, and freeform dividers visually.

Made for beginners

The workflow stays visual from the first measurement to the final printable files without requiring CAD experience.
