This project contains some experiments with Lego DUPLO and personal fabrication. Similar examples can be found at http://www.thingiverse.com/tag:duplo.

Background

Design

Dimensions and more information about Lego and Duplo bricks can be found at http://www.robertcailliau.eu/Lego/.

If you cut material you must think about the width of cuts, for instance laser cutters burn away some material. I expect this to be about 0.25mm, so I'd naturally get the required gap between parts.

Unfortunately I have not found a satisfying CAD software for 2D design, so I started with Inkscape.

You can use any stable material but plywood might be the best choice. 2mm, 3mm, 4mm.

Production

Either you have access to a 3D-printer, 2D-Cutter etc. or you must order the parts at some service. I tried formulor.
