Faceted vase cast in cement

Printed using PLA. Printed exterior as a thin shell with bottom skin. Printed interior cylinder. Used Rapid Set CEMENT ALL, poured in to the vase, pushed in the interior to make a void and taped it down to hold the interior tube in place. Let cure for 6 hours then put it in HOT water. The PLA becomes a thick skin that can be carefully cut and peeled away. Be careful. It's really easy to scald yourself working over the hot water.
