Nice, pretty big vase, with on the top a flower shape, and on the bottom an hexagon shape. That's where the name 'flowagon' came from :-O. That's a pretty cool name right? ;-)
I printed it with yellow PLA, and it came out really nice like you can see. There are some overhangs (not that bad though) at the bottom, but my printer printed these with no problems, and they're really smooth anyways! :-) Print took about 5 hours I think on my printer.
Anyways, you can find the print settings I recommend under here, and if you have any questions, please ask me!
PLEASE tell me when you made it!!! I would really love to hear that! :-)
Spiralize outer contour;
Print slowly (not higher then like 30mm/s);
I recommend using a skirt/brim;
