ROSE Mechanised Articulated Flower

So I made one of these as a gift for the girl I just started dating, she absolutely loved it... She showed it off to her friends and family - she said they thought it was "The Cutest Thing!"

I couldn't figure out how to print at 0.10mm layer height because it would keep falling off... but soon as I changed to 0.15mm layer height everything was fine. I'm thinking there's something with my Z-axis offset, I generally just let the printer adjust it automatically through the print calibration. I'll have to figure out how to do it manually for the future.
