First, I have to give a huge thanks to ESSEFF3D who did the real design on this (and has lots of other Zelda items)... the core design was really solid, and is basically unchanged in my remix... I wouldn't have taken this on for my daughter without such a great starting point.
My daughter went to comic-con as Zelda... so of course she needed a crown. Problem was that the original design was too small (headband) and appeared a bit thick (chunky), and she wanted it to be more delicate.
Things I changed in this design:
1) The headband is now customizable... measure your head with a sewing tape measure (in mm) and you can use the customizer on this to create your personalized headband.
2) The headband now has the square mounting blocks built into them. I added a fillet on the bottom and was able to print the headband, with these blocks, without supports
3) I added a mounting hole to the back of the band for the backpiece.
4) I added a pin into the design of the backpiece to properly position it in the band
5) I slimmed down every component (leaves, centerpiece, backpiece, etc) by at least 25%
6) I hollowed out the gemstones (prints nice in translucent filament)... (I may have been able to just print the original with 0% infill, but why not make the design hollow)
7) I provided all the STLs in the orientation that they should print.
8) I've included a 570mm band STL (the one my daughter used... which I created before designing it in customizer.
Good luck, and enjoy.
I was able to print most without supports in the orientation shown by the STL (including the band with built in mounting brackets), but some of the larger leaves benefit from having supports added as their backsides are rounded..
Be aware that the left and right versions of the leaves are different... take a look at the images to compare. There is a small "peg4back" that you'll need 2 of, these allow easy positioning of the 2 halves of the back piece together.
Super Glue is your friend... position the components one by one and glue away.
After painting, add the gemstones in translucent filament.
