The pieces are so small I printed them @0.1 with a 100% infill to give it some weight. The brooch is roughly 50mm x 50mm x 6mm.
The brooch is printed separate from the gems so you can print the gems a different color or use different color stones in their place.
I used silver spray paint on the brooch and then we used black paint to give it a darker look to the areas where the orange gems are.
I used Gorilla super glue to set the gems. The gem holes are 1mm bigger then the gems so they will be easy to dry fit them. The gems will print out on the build plate the same way the go into the brooch.
Example : When you print out the orange gems the three on top will be placed in the brooch as they as on the build plate and the bottom one will fit into the bottom slot on the brooch. The green and white gems will be placed in the brooch as they are on the build plate (left gem on the build plate will go in the left side of the brooch (as in the photo above))
