I thought it was worth posting my error,
"low" support setting (on Davinci Pro)
Attempted to print upright in one piece but as the images show the support material buckled..... but i kind of like the warped "tear drop"
It will require a fair bit of post processing but i still love it.
I will try again but in two pieces. split just under the top sphere.
Great design all in all.
