This is a remix from Bridal Floral Tiara  by Lorenz Nimmervoll, cater for easier print without any support. This require remove of the extreme overhand >45degree side curl. Added a tear-drop pearl, enlarge the whole tiara for grownup head size or Queen size. Increase the height of the tiara to give more volume and grandeur. Chamfer some sharp edges. 

Print using PLA

Without Support.

Provided STL, f3D , Step file for modification. 

Below is initial version as later I found that the tiara has other >45 degree overhang, latest files has final changes. However I am already satisfy with 1st print without support. Added holes for gem stones in the latest version!
