Hollow Spheres

thingiverse

I designed several spheres made up of two and three sets of parallel rings. Printed through Shapeways, they withstood the smallest print thickness test and proved strong enough to withstand a drop without shattering (results may vary depending on material). The picture is printed in "White Strong & Flexible" material from Shapeways. This design could also serve as an excellent stress tester for FDM printers.
