Free Download: uBrick LEGO® Generator

Hey everyone! I just released uBrick Generator, a free open-source Blender add-on that generates parametric LEGO®-compatible bricks — fully manifold and ready to slice for 3D printing, with zero Boolean operations.

Features

  • Parametric brick generation: any size from 1×1 to 32×32, stackable heights
  • Fully manifold mesh (0 open edges) — works in PrusaSlicer, Cura, Bambu Studio out of the box
  • Correct face normals on every surface — no blue faces, no slicer artifacts
  • Hollow shell with real wall thickness (LEGO-spec 1.2 mm)
  • Closed top plate (solid box, 1.2 mm thick)
  • Anti-stud tubes for proper brick-to-brick connection
  • Internal ribs between tubes
  • Tolerance parameters exposed in the F9 panel for tuning to your printer and filament
