How to measure your drawer
1. Inside width: Measure from the left wall to the right wall at the front, middle and back. Record the smallest reading.
Your drawer, mapped out.
Printed perimeter: 14 mm left/right and 12 mm front/back.
Calculated as you type. You can adjust these measurements before reviewing your layout.
Measure your drawer and understand the result
Choose the intended printed footprint
Measure the usable inside width and length at their narrowest points. Check corners and obstructions where the base will sit. The dimensions you enter become the full outer footprint of the printed base, so allow room to install and remove it before entering your final sizes. The planner accepts 42–1,260 mm on either axis.
Check closing height separately, with the contents in place. This calculator does not measure your drawer height or automatically confirm closing clearance. Use our drawer measurement checklist before requesting prints.
How the grid and perimeter are calculated
Each grid cell has a 42 mm pitch. Divide the entered width and length by 42 and round down to find the whole columns and rows. Multiply those counts by 42 to find the grid footprint. The remaining width and length form a printed perimeter, divided equally between opposite sides.
For example, 280 × 360 mm gives 6 × 8 cells. The grid occupies 252 × 336 mm, with 14 mm of printed border left and right and 12 mm front and back. For 300 × 300 mm, a 7 × 7 grid occupies 294 × 294 mm and leaves 3 mm of printed border on every side.
That border is part of the base. It is separate from installation clearance and does not create more cells for boxes. Forty-eight cells can hold several larger boxes; they do not mean forty-eight individual bins.

- Grid: Whole 42 mm cells for boxes. The entered width and length are divided by 42 and rounded down.
- Printed border: The leftover width and length, split equally between opposite sides. It is printed as part of the base, so it is not empty space and adds no cells.
- Drawer clearance: The printed base fills the 280 × 360 mm you entered. Room to insert and remove it has to come from outside that size. We cannot measure your drawer or recommend one allowance; the dashed wall is hypothetical.
Choose Add side rails to close the gap between the drawer and boxes with raised rails supported at both ends. Rails need more than 2.3 mm of printed border on every side. Leaving the option off keeps the full printed base border. Check the generated model and drawer closing clearance before ordering.
Planning limits and printability
Arrange rectangular boxes up to 5 × 5 cells. All boxes share one height from 11 to 240 mm, entered as whole millimetres. Empty cells retain the base; leave every cell empty for a base-only plan. The calculator always includes a base. For bins alone, use suitable authorized files through Upload or ask about your existing setup.
The grid pitch describes placement. Check the generated model for the actual inside cavity and room to retrieve your contents. The planner's top and isometric diagrams are illustrations, not prepared manufacturing models or tested physical fits.
A selectable box must still fit the usable print area. This generator's 5 × 5 box measures 209.5 × 209.5 mm outside. As an example, a 256 mm bed with 5 mm margins on each edge has only 246 mm of usable width, so that box fits. Preparation still checks the actual print settings and may require a smaller box. It does not silently reduce the margins or cut a box into pieces.
From your plan to a reviewed quote
Planning stays in your browser until you deliberately choose Generate preview, when offered. That step requires your email and prepares the model for review. Check the assembled model and every plate, choose an available material and review the full quote before paying. Current product availability and manufacturing checks determine which layouts can proceed.
