Now there is a time to introduce you 3 ways how to print this beautiful model.
1st - Water tight vase (Polygon Vase - solid.stl)
My most favourite print settings gives you watertitght vase in 10 hours with low material consumption. (No spiral mode). I made three vases with this settings and all of them are watertitght and more strong.
Get these values into the slic3r.
Perimeters - 3 (with 0.4 mm nozzle) // this paremeter gives you wall thickness and watertightness.
Infill - 0% // this parameter gives you hollow vase without any ribs inside.
Top Layers - 0 layers //this parameter gives you open top.
2nd - Spiral vase (Polygon Vase - solid.stl)
Spiral vase is very quick. I made one under 4 hours with 0,15 layer height.
3rd - edited model (Polygon Vase - hollow.stl)
For those who want hollow model due to their slicer software.
Thank you so much and leave me a comment please, I will answer you in few hours :)
