Parametric circular LEGO-compatible plate

Parametric generator for parametric circular LEGO compatible plate

It requires openscad. You can specify diameter N in LEGO units in the openscad file
two examples provided for diameter N=12 and N=22

You need to generate the polygon mesh (CGAL) to export as STL

Remarks:

• the rendering can take some time for high values of diameter N
  biggest N tested for N=22 on a core I7 desktop computer
• although design was tuned, there might be some little holes on the side for some value of N (check before printing)
