has these options for configuration.

//controls the sarrus linkage height and width linkageheight=80; linkagewidth=50;

//hole radious in mm holewidth=4; outerhole=10; //Height of the tear triangle tearangle=90;

linkageholeangle=90; baseholeangle=0;

Please not that this is still fairly early. I haven't added many features. The idea is that you put a screw through the hole and separate the joint with 2mm washers. Hopefully this will put the transverse motion within tolerance needed to build a Cartesian robot.
