OpenSCAD Layout Grid

OpenSCAD Build Surface Grid

OpenSCAD Build Surface Grid

This OpenSCAD module spreads an array of cubes across the otherwise featureless preview window, so I know whether the gizmo I’m building or the parts I’m arranging actually fit on the Thing-O-Matic’s build platform. This doesn’t get out to the very edge, but if it looks close, then I should pay more attention anyway.

module ShowPegGrid(Size) {

 for (x=[-5:5])
  for (y=[-5:5])
   translate([x*10,y*10,Size/2])
    cube(Size,center=true);

}

ShowPegGrid(1.0);

You obviously don’t want to extrude these things, so put the ShowPegGrid() statement inside an if, so you can turn it off for the final build layout.
