Designing bins

Compartments and dividers ​

Screws, washers and nuts in one open bin end up as one big mix. Dividers fix that. In the Gridfinity Layout Tool, you can split a bin into a neat grid or draw compartments of any size. You can also tilt dividers for cutlery, or print dividers that you can move later.

Everything on this page is in the Interior group of the bin designer. Start by picking one of four interior styles:

StyleWhat you get
Grid dividersA grid of compartments with fixed walls. Merge cells for larger compartments.
BentoCompartments of any size that you draw on a canvas.
Removable dividersSlots in the walls, and separate divider pieces that you push into them.
Custom cutoutsA solid bin with cutouts in the shape of your tools. See Cutouts.

The first three styles need a rectangular footprint. Not sure which to pick? Start with Grid dividers. You can move to Bento later and keep your compartments.

Set up the compartment grid ​

  1. Pick Grid dividers.
  2. Set Columns and Rows, from 1 to 12 each.
  3. Read the size of the smallest compartment under the steppers.

Know the size you need instead? Open Set by size and type the smallest opening you need in millimeters. The bin designer picks the largest number of columns and rows that keeps every compartment at that size or larger. The compartments at the edges can be wider.

With two or more compartments, two more controls appear:

  • Divider thickness: the same values as the wall thickness, from 0.4 to 2.6 mm.
  • Divider height: Auto or a height in millimeters. With the stacking lip on, Auto stops just below the feet of a bin stacked on top.

A compartment cannot be smaller than 5 mm. When you change the grid, the bin designer moves compartment labels by position, and tells you if it clears some.

Merge and split compartments ​

  1. Drag across two or more cells. When you let go, they merge into one compartment.
  2. To split a merged compartment again, click it.

A merged compartment is always a rectangle. Made a mess? Reset above the grid sets all compartments back to a uniform grid.

A drag across the two top left cells of a 4 by 3 compartment grid merges them into one compartment. The bin then shows one long compartment at the back left.A drag across the two top left cells of a 4 by 3 compartment grid merges them into one compartment.

Tilt and lean dividers ​

Diagonal dividers makes wedge-shaped compartments, for example for cutlery that gets narrower at one end. The toggle is under the compartment grid.

  1. Turn on Diagonal dividers.
  2. Click a divider on the grid, or pick it in the list.
  3. Set Angle to turn the divider in plan, up to 60°.
  4. Set Lean to stand the divider over, so contents rest at a slope.
Diagonal dividers is turned on, and the divider between Comp 1 and Comp 2 is picked in the list. Angle and Lean are set to 15°. The bin then shows the divider at an angle, and it leans to one side.Diagonal dividers is turned on, and the divider between Comp 1 and Comp 2 is picked in the list. Angle and Lean are set to 15°. The bin then shows the divider at an angle, and it leans to one side.

The lean has a limit for each compartment, and the panel shows it with the clear opening. Apply lean to all parallel dividers copies the lean to the other dividers that run the same way. Fine-tune holds a Shift control that moves the divider. To start over, click Reset to straight.

WARNING

Look at your scoops and label tabs after you tilt a divider. The bin designer removes scoops, label tabs and inserts along a tilted divider.

Draw compartments with Bento ​

Bento gives you a large canvas where you draw each compartment, like a bento box. It needs a wide screen. On a small screen, the card shows the grid editor of Grid dividers instead.

  1. Pick Bento and click Bento workspace.
  2. On an empty canvas, choose the drawing grid. Compartments snap to it.
  3. Drag on the canvas to draw a compartment.
  4. Drag a compartment to move it, or pull its handles to change its size.
Bento is picked, and Bento workspace is clicked. On the empty canvas, the 8×6 grid is picked, and three compartments are drawn with drags. The right handle of the last one is pulled to make it wider. The bin then shows the three compartments.Bento is picked, and Bento workspace is clicked. On the empty canvas, the 8×6 grid is picked, and three compartments are drawn with drags. The right handle of the last one is pulled to make it wider. The bin then shows the three compartments.

A few more moves:

  • Shift+click a second compartment that touches the first to fuse them into one L, S or U shape.
  • Alt+drag a compartment to make a copy.
  • Drop a compartment on the Stash shelf to keep it for later. The shelf holds up to 36 compartments.
  • Use Walls in the compartment panel to shift or turn a wall between two compartments.
  • To give one compartment its own color, open Color in the compartment panel. Pick Floor or Floor + walls. The color prints in a second filament.

Each empty cell prints as its own small pocket. Turn on Merge leftover space to make one pocket from each open area instead.

Raise a compartment floor ​

Small things in a deep compartment are hard to pick out. Floor raise lifts the floor of one compartment, so a short item sits nearer the rim. Tall items in other compartments keep the full depth.

  1. In the Bento workspace, select a compartment.
  2. Drag Floor raise to the height you need, in millimeters.
The bin shows five compartments of full depth. The narrow Tips compartment is clicked on the Bento canvas, and Floor raise is dragged to 24 mm in the compartment panel. The bin then shows the Tips compartment with its floor near the rim.The bin shows five compartments of full depth. The narrow Tips compartment is clicked on the Bento canvas, and Floor raise is dragged to 24 mm in the compartment panel. The bin then shows the Tips compartment with its floor near the rim.

The raised floor is solid, and the infill of your slicer keeps it light. The bin designer keeps at least 3 mm of depth above the raised floor. A finger scoop climbs from the raised floor. For a Grid dividers bin, pick Bento: the compartments stay the same, and you get the same control.

Use removable dividers ​

Not sure how you'll split the bin yet? Removable dividers cuts slots into the walls. The divider pieces print separately and slide into the slots, so you can move them later. The export includes the pieces, and an STL export with pieces downloads as a ZIP file.

  1. Pick Removable dividers.
  2. Under Layout, pick Even spacing.
  3. Pick a Direction. Pick Both for pieces in both directions.
  4. Set Compartment width, from 10 to 50 mm.
  5. Set the height, thickness and fit of the pieces.
Removable dividers is picked, with Even spacing and Both. Each Compartment width is set to 40. The bin then shows slots in its walls, and the divider pieces lie beside it.Removable dividers is picked, with Even spacing and Both. Each Compartment width is set to 40. The bin then shows slots in its walls, and the divider pieces lie beside it.

For pieces in one direction only, pick Vertical or Horizontal.

The divider pieces have these controls:

ControlRange or default
Divider heightAuto, or 5 mm up to the auto height
Divider thickness0.8 to 2.4 mm, default 1.6 mm
Fit tolerance0 to 0.3 mm, default 0.25 mm. Use more for a looser fit.
Floor grooveOn by default: a 0.8 mm channel in the floor holds the bottom edge.

Pieces too tight or too loose? Keep the default Fit tolerance for a first print, then adjust it.

To draw your own grid, pick Custom. Its Merge and Split controls shape the grid. The bin designer then makes pieces that match the grid you drew.

The walls must be 0.8 mm or thicker for slots. Removable dividers turn off the compartment grid, label tabs, the finger scoop and the interior fillet. You cannot use them with tilted dividers or a Nesting body.

Interlock cross dividers ​

When you pick Both, Cross dividers sets how the two sets of pieces meet:

  • Interlocking: full-length pieces in both directions with notches that lock them together.
  • Per compartment: full-length pieces in one direction, with short pieces between them. Pick the long direction in Full-length direction. Use a divider of 1.2 mm or thicker.

With interlocking pieces, Piece lengths gives shorter pieces too:

  • Full: one wall-to-wall piece for each slot.
  • Snappable: each piece has score lines, so you can snap it to length. Use a divider of 1 mm or thicker.
  • Length set: a set of pieces that span one or more compartments, each with the correct notches.

When it goes wrong ​

The dividers stop below the rim ​

Turn off Stacking lip in the Base group. Dividers at Auto then reach the rim, but other bins can't stack on this one.

With the lip on, Auto is the tallest a divider can be. A bin stacked on top puts its feet just above the dividers. See Stacking.

The bin has no slots for the removable dividers ​

Set Wall thickness to 0.8 mm or more, in the Shape group. While the wall is thinner, a warning shows above the slot controls.

The bin designer cuts slots only in walls of 0.8 mm or thicker.

The column or row count won't go higher ​

Make the bin wider or deeper, or make Divider thickness thinner. Then add the column or row.

Each compartment must stay at least 5 mm wide. The bin designer ignores a grid change that makes a compartment smaller.

Some compartment labels are gone after you change the grid ​

Press Ctrl+Z (Cmd+Z on a Mac) to undo the change. The labels come back.

When you change the columns or rows, each label moves to the compartment at the same position. The bin designer clears a label with no compartment at its position, and a message tells you how many.
