This is a pendant for a necklace with a diameter of 50mm.
In case you do not have a matching stone for the inset (like me ;-) ), I added a model for a matching stone which can be glued into the hole after printing.
The tolerance of pendant and stone is 0.2mm.
I printed the pendant itself with a resolution of 0.2mm and 25% infill.
The stone is printed with 50% infill, 0.1mm layer height, 10 top layers, and 5 outer perimeters, because I sanded it after printing (starting at 120 grid going all the way up to 12000).
Not necessary, but I wanted to test my micro mesh sandpaper anyways. So I startet to sand the stone with 120 grid sandpaper and went all the way up to 12000.
Because I sanded by hand the process took around 2 hours.
