Summary

I made this vase for violets and added a dish to retain the water. I used the beautiful Spiral Vase made by Yllonnoce - http://www.thingiverse.com/thing:550604 and Netfabb to cut on the height.
These on the photos are with 9 x13 cm. On the slicer, I scaled up all things to 1.4.
I used soldering iron to do the holes on the bottom of the vase that need to be done.
