Here is a Jewelry set i designed for the #ANYCUBIC3D competition
The set consists of a bracelet, earrings and necklace.
The gem stones are designed ...to be printed as a single strip, flat on the printer bed without supports, thus it can be printed in a different color, and are joined by a thin connectors keeping the stones together so that they can easily be glued into their recesses. This can be seen in the image attached in PrusaSlicer
Print the stones in a shiny filament for a really beautiful effect.
The earrings are designed so that metal earring hooks are attached to complete them - example of hooks in pictures.
The necklace is also designed for a chain with clasps and loops to be connected to complete the back of the item.
i have attached only 3d renders of the design as i am unable to get filament currently during the lockdown.
The Bracelet would need supports for printing.
the Earrings and Necklace would really only need supports for the loop connectors.
