Design a perfectly sized organiser tray online in under a minute, then print it — no CAD skills required.

What this tool does

Define the outer dimensions of your tray, set the number of rows and columns, choose wall thickness, and generate a custom component organiser as a 3D model. All compartments are calculated automatically. Export as OBJ or GLB.

Frequently asked questions

▶ Can I have unequal compartment sizes?

Currently compartments are equal. For unequal sizes, export OBJ and modify walls in Blender.

▶ What infill should I use for printing?

15–20 % infill is sufficient. Use 3–4 perimeter shells for strong walls.

▶ Will it fit in my drawer?

Measure your drawer and enter those exact dimensions. Allow 0.5–1 mm clearance on each side.

▶ Can I make a lid?

Modelling a lid isn't built in yet — design one in Blender using the tray dimensions as reference.
