# Drawer organizers, trays and holders that fit exactly

> Describe your drawer or shelf and what goes in it. SpeakCAD generates dividers, trays, bit holders and bins sized to the millimetre. STL, 3MF or sliced G-code export.

Off-the-shelf organizers never match the drawer. Tell SpeakCAD the inside dimensions of the space and what you want to store, and get a tray with compartments sized for the contents.

## Compartments from a description

Say how many compartments you need and either their sizes or a ratio; the AI computes the divider positions with consistent wall thickness. Ask for finger notches, rounded inside corners for easy cleaning, or a slight taper so trays stack.

## Fits standard systems

Want compatibility with a grid storage system you already use? Give the base unit (for example 42 mm squares) and SpeakCAD sizes the footprint to multiples of it, with a lip for stacking.

## Tips for fast, strong prints

- 1.2 mm walls print in two perimeters and are plenty for light contents; ask for 1.6 to 2 mm for tool trays.
- Rounded internal corners reduce print time and stop dust accumulating.
- A 0.6 mm chamfer at the bottom edge avoids elephant's foot and lets trays slide in.

The [box generator](/box-generator) covers boxes with lids and dividers, and the [holder generator](/holder-generator) holders sized to one object or a block of pockets for bits and hex keys; both start free from a shape you finish with the hand tools.

## Prompts to try

- A drawer organizer 150 x 100 x 40 mm with three compartments in a 1:1:2 ratio, 1.6 mm walls, finger notch on each divider.

- A holder for 12 screwdriver bits (6.35 mm hex, 25 mm long) in two rows, angled 15° for easy reading, labels area on the front.

## FAQ

### Can it make bins compatible with a grid system?

Yes. Give the grid pitch and height unit, and the AI generates a compatible footprint and stacking lip. Check one unit before printing a full set.

### How do I split a large tray across a small bed?

Ask for the tray as two halves with alignment pegs, or as separate modules that butt together.

## About SpeakCAD

SpeakCAD is the most intuitive CAD for 3D printing, made for people who own a 3D printer and need a part that fits something they have: tap a face and type a size to shape it with simple tools, or describe it to the AI, on your phone or computer, and download a print-ready STL, 3MF or G-code sliced for your printer.

SpeakCAD works inside ChatGPT and Claude as a plugin (an MCP server): ask the assistant for a part with its measurements and SpeakCAD's own CAD AI designs it, shows it in 3D in the chat and hands over a print-ready STL, 3MF or G-code sliced for your printer.
