I designed this from many many Icosahedrons' overlaid on each other. Then had fun with the formation. Vase mode print, make sure to use that mode in your slicer. 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 wall thickness while in vase mode. I hope you enjoy this model DWTC
