About this 3D model
This thing was made in OpenSCAD with the following code: rotate([0,0,0])difference() { translate([10,2,2])sphere(10); rotate([90,90,90])cylinder(20,10,10); } rotate([60,0,0])difference() { translate([10,2,2])sphere(10); rotate([90,90,90])cylinder(20,10,10); } rotate([120,0,0])difference() { translate([10,2,2])sphere(10); rotate([90,90,90])cylinder(20,10,10); } rotate([180,0,0])difference() { translate([10,2,2])sphere(10); rotate([90,90,90])cylinder(20,10,10); } rotate([240,0,0])difference() { translate([10,2,2])sphere(10); rotate([90,90,90])cylinder(20,10,10); } rotate([300,0,0])difference() { translate([10,2,2])sphere(10); rotate([90,90,90])cylinder(20,10,10); }
