Sort the brick box with a shake.
Stacking trays with a grate in each. Tip the pile in the top and shake. Big parts stay up top, each tray down catches a smaller size, and the tiny bits end up in the base.

How it works
- step 1
Pick the levels
Start from a ready-made set of trays, from a quick big and small split to five levels. Change any tray's holes or height.
- step 2
Print the fit test
A small tray and base. Check the tray drops on and sits without rocking.
- step 3
Print and sort
Print each tray grate down, stack them, tip the bricks in the top and shake side to side.
The generator runs OpenSCAD in your browser, so nothing is uploaded. It is a parametric model: a size change is a setting, not a new design.
Questions
How does the brick sorter sort?
Each tray has a grate with smaller holes than the one above. A part falls through until it meets a hole too small for it. The hole sizes are picked from brick widths, so each tray catches parts of a set width in studs.
How many levels should I make?
Three is the best start: big parts, 2-wide and 1-wide. That is the same split as LEGO's own Sort & Store. Go to four or five if you build a lot and want plates and odd widths apart. Two is enough for young children.
Does it work with LEGO and other bricks?
Yes. The hole sizes are worked out from the standard 8 mm stud spacing, which LEGO and the compatible brands share. It is not made by or linked to LEGO.
What size printer do I need?
Every tray prints on a 220 mm bed, like a Creality Ender V3. The large size is 210 mm square. The small size, 120 mm, fits mini printers too.
Is it free? Do I need to install anything?
It is free and runs in your browser. The generator runs OpenSCAD locally, so nothing is uploaded and there is nothing to install.

Hi, I'm Will. I make these for jobs around my own house and garden. I had a sieve box like this as a kid. Every part is sized to print on a 220mm bed, like a Creality Ender V3.
