Tip: pieces flat on white paper, studs up, not touching. A finished model works too.

A car, a robot, a character, a building: Mister Blocks researches it and designs it in real pieces with step-by-step instructions. About 3–6 minutes.

Instructions · page 1

Three steps. Real bricks.

  1. Snap your pieces

    One photo of the pile, spread out on paper. Wheels, plates and odd bits all count.

  2. Get four builds

    A car, a work truck, something that isn't a vehicle, and something that flies. With 3D steps.

  3. Build, then chat

    Send a photo of what you made, or say what doesn't fit. Mister Blocks fixes the model.

How custom LEGO instructions are made

Mister Blocks first looks up what you asked for: its shape, its colours, the details that make it recognisable. Then it designs the model piece by piece in standard LEGO bricks, plates and slopes, and a checker tests every stud and wheel. Problems go back to the designer until the model holds together.

You get a 3D model you can turn around, steps you can follow one by one, the full parts list and a printable booklet. Don't like something? Say "make it red" or "add a ladder" in the chat and it changes the model.

Yes, with a few builds per person per day.

Before you see it
