Design and print 3D containers that fit your drawer exactly.

Get back hours of print time and free spools of filament on containers that almost, but don't quite, fit your drawers.

Start making containers. It's free!

The Container CAD project page for a desk drawer, with six numbered callouts: 1 start with your drawer size, 2 choose a grid that fits, 3 drag to design your layout, 4 fine-tune every container, 5 preview your fit in 3D, 6 download your files and print. Settings sit on the left, the grid and parts list in the middle, the 3D preview on the right.

Measure. Layout. Print.

Finish your first grid in 5 minutes.

Measure

Grab a tape measure. Type in the width and depth of your drawer. That is the only measuring you will do.

Layout

Pick a grid. Drag out boxes where you want them. Big ones, small ones, whatever fits your stuff.

Print

Download the files. Send them to your printer. Drop the containers in. Done.

It's all free, including the downloads

Design as many drawers as you like. Preview them in 3D. Download every STL file and print at home.

One day we might monetize but for now, it's all free.

How you get a perfect fit

You choose the gaps. We do the math.

A drawer seen from above holding four containers, with a blue band labelled edge gap running around the inside of the walls.

Set the edge gap

The space between the drawer walls and the outer containers.

Two containers side by side seen from above, with the narrow yellow space between them labelled cell gap.

Set the cell gap

The space between neighbouring containers.

A 2x1 container measured at 201 mm sits above two 1x1 containers measured at 100 mm plus 1 mm plus 100 mm, showing the 2x1 spans both cells and the gap between them.

We work out every size

We calculate the container from the drawer, incorporating the gaps.

For example: a drawer 405 mm wide with 4 columns, a 1 mm edge gap and 1 mm cell gaps gives cells of exactly 100 mm. A 2x1 container comes out at 201 mm, two cells plus the gap in between.

Make the containers your own

Four adjustments to make your containers just right.

A purple container cut open, with four numbered callouts: 1 on a hatched wall for its thickness, 2 a yellow arrow from floor to rim for height, 3 on the rounded top corner, 4 on the hatched floor for its thickness.

Wall thickness
How thick the four walls are. Thicker is stronger. Thinner saves filament and prints faster.
Height
How tall every container is. Pick a height that fits your stuff and your drawer.
Corner radius
How rounded the vertical corners are. Sharp for a crisp look. Rounded for friendly.
Floor thickness
How thick the floor is. A thicker floor stays solid when picked up and grips the print bed better.

Two kinds of grid

Stretch for an exact grid. Square if you want rotating containers.

Stretch

A drawer seen from above divided into 4 columns and 3 rows of equal blue cells that fill it edge to edge, labelled 4 across and 3 deep.

Tell us how many columns and rows. The cells stretch to fill the drawer exactly.

No leftover strip.
Cells are rectangles, so a 2x1 and a 1x2 are different parts.
Best when you want the drawer full, edge to edge and you don't expect to rotate containers.

Square

Every cell comes out a perfect square. A container then fits the same way turned a quarter turn.

Containers can be rotated and still fit nidely
Choose a specific size in mm, or choose how many grid cells across or deep
The leftover strip can be filled with partial containers (good for thin stuff like rules or pencils)
