Free Custom Bin & Sorting Tray Generator for 3D Printing

Create perfectly sized storage bins, sorting trays, drawer organizers, and parts bins — all customized to your exact needs. This parametric bin generator runs entirely in your browser using advanced CSG (Constructive Solid Geometry) powered by the Manifold engine. Adjust dimensions, grid layout, wall thickness, corner radius, and more. Download a print-ready STL file instantly.

Popular Use Cases

Desk & Workshop Organizers

Custom-fit trays for pens, tools, screws, electronics components, and hobby supplies. Size it exactly to your desk drawer or shelf.

Parts Bins & Screw Sorters

Keep small parts organized with multi-compartment bins. Customize the grid to match your sorting needs — from M3 screws to resistors.

Drawer Inserts & Dividers

Measure your drawer and generate a perfect-fit insert. Set exact dimensions, number of compartments, and wall thickness for a snug fit.

Etsy & Print-on-Demand Products

Generate custom organizers for customers. Quick turnaround on made-to-order bins with exact specifications — perfect for Etsy sellers.

How It Works

Adjust dimensions using the sliders or type exact values
Set the grid layout (rows × columns) for compartments
Customize wall thickness, floor thickness, and corner radius
Optional: add a stacking lip or label edge

Recommended Print Settings

Layer height: 0.2mm (good balance of speed and quality)
Infill: 15-20% (bins don't need high infill)
Walls: 3 perimeters for durability
Material: PLA for general use, PETG for heat resistance
Supports: Not needed — the design is optimized for supportless printing

Frequently Asked Questions

What is a parametric bin generator?

A parametric bin generator lets you create custom 3D-printable storage bins by adjusting parameters like width, depth, height, number of compartments, and wall thickness. Unlike fixed STL files, every dimension is adjustable to your exact needs.

Do I need to install any software?

No. This tool runs entirely in your web browser using WebAssembly. There's nothing to download or install. The 3D model is generated on your device — your data never leaves your computer.

What file format is the output?

The tool generates a binary STL file, which is universally supported by all 3D printing slicers including Cura, PrusaSlicer, Bambu Studio, and OrcaSlicer.

Can I make bins that stack?

Yes! Enable the "Stacking Lip" option to add a small lip around the top edge that lets bins nest securely on top of each other.
