Copy all the scad files into a common directory.
The code has been tested using ABS, printed at .3mm layer height with 1 extra shell and 50% infill.
The parameters for the size of the bot, the board size, etc. are all contained in the file newsumo.scad.
It can be setup to generate a 3D view or printable views for the top, bottom, and sides. Just uncomment the line in newsumo.scad for what you want.
