Update : 03/01/2016 I've added a 3D printed mold pattern for sand casting a lead weight to fir in the bottom of the water tube. Also the water tube will require sealing with PVA or epoxy. -------------------------------------------------- The vase is designed to be printed without supports. The vase in the video was printed in PLA , with 0.15mm layer heights. To use the water tube, fill with water and then lower the vase over it... add follower :-) With some flowers the vase is a bit top heavy. If so add some weight to the base of the tube.
