this vase was created by a happy accident while playing around in openscad.
and as happy as i am now i'd like to share it with you...
UPDATE 5th October 2017
Version 3 is uploaded. This version should be in the right scale (200mm Height)
the design of this vase is based upon a custom made guitar pick/plectron (PLActron - the customizable & biodegradeable guitpick), which is rotated 240 degrees around the z-axis an extruded along a sine in z.
casually inspired by:
this model is scaled to be printed with 20cm height,
which should fit most printers and most flowers.
you can download not one, but 3 different versions of this vase.
while the smallest with 32 segments adds some interesting geometry, the 500seg is the way to go if you want a smooth shape,
if you can't decide take the 100seg-version
*EDIT 2018-04-15: I#ve removed the 32 and 500seg-version, because they were out of scale and made made no significant difference to the new default 100seg-Version
slicing suggestions for Cura 15.02.1
printing time with these settings on an Ultimaker 2 is under 6 hours
this model is quite easy to print, no overhangs and no detailed structures, you could print it in 0.3mm > Layers without much hesitation.
If you have problems getting this vase watertight, try raising the values for Shell Thickness and/or Bottom Thickness. You could also try to set the Shell Thickness to a non-multiple of you Nozzle Size, so the Outer Walls overlap.
