FROM A LITTLE IDEA TO A REAL THING

Your next brick starts here.

01

Draw outside the rectangle.

Choose a starting shape or clear the grid and draw your own. Each square is an 8 mm stud position. Touch and drag work too.

02

Give your idea another dimension.

Set the drawing height in bricks (9.6 mm) or plates (3.2 mm). Draw sets that height; Raise and Lower change each cell by one selected unit. Each column grows from the base, creating a supported stepped piece.

03

Take it off the screen.

Rotate the preview, then download a binary STL in millimeters. The hollow underside uses short support tubes and a flat ceiling, at most 8.6 mm deep. Shorter sections reduce that depth across the shape; taller sections add material above it. Solid base creates a solid part. Fit varies by printer and material, so start with a small test print.
