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 and divider thickness, corner radius, and more. Add finger scoops, an interlocking stacking lip, a label tab, or filament-saving floor holes. Check the fit against your printer's build plate and 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

  1. Adjust dimensions using the sliders or type exact values
  2. Set the grid layout (rows × columns) for compartments
  3. Customize wall, floor, and divider thickness plus corner radius
  4. Optional: add a stacking lip, label tab, finger scoops, or floor holes
  5. Select your printer to confirm the bin fits your build plate
  6. Click Download STL to get a print-ready file

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 raised rim around the top edge and a matching recess in the base, so identical bins interlock securely when stacked.

What are finger scoops?

Finger scoops add a curved ramp along the front of each compartment, like Gridfinity bins. Small parts such as screws, nuts, and SMD components slide up the curve so you can pick them out easily. The curve is concave, so it prints without supports.
