Lego bricks

A parametric modeling of Lego (TM) bricks with Freecad. In the included spreadsheet, there are 3 essential parameters: choose the width and length in number of bumps and choose a standard height or low height. The brick will immediately take the chosen dimensions. You can then export it as a step model and build a collection of pieces of different dimensions. The model differs from Lego in two aspects: no hole under the bumps, and no reinforcement underneath.
