I designed this from 2 hearts stacked on top of each other. Vase mode print, make sure to use that mode in your slicer. Due to limitations of vase mode printing I had to chop the top (the bottom really) of the stacked heart. Prints without supports and I recommend at least 1mm walls. I print with a .6 nozzle and use 1.2 line width. This give the vase 2 walls while in vase mode. I hope you enjoy this model DWTC
