This vase looks stunning but I made it with having 4 walls and 10 bottom shell layers to make it sturdy and stronger. Looks superb in silk gold! Thank you for this design as I also like how it has a broad mouth at the top to fit many flowers.
One way to help get rid of the gaps in vase mode prints like this is to increase the extrusion width/line width. A 0.4mm nozzle can do up to 0.6 - 0.8mm extrusion width.
Printed with a PLA from Kexcelled . Really nice pot, my wife liked it and answered it on a shelf with some fake seedlings. Great design and fast printing,
