Nice work....
Prepared to production STL and 3DM models of earring.
Weigth is pretty heavy. But have you seen the real biker loving thin foil instead of solid metal?
Model volume is 650mm^3 (410mm^3 for bigger and 240mm^3 for smaller parts).
Estimated weight for sterling silver is ~6.5g (really less).
STL files are made for printing.
For CNC machining (that gives better surface and pattern quality) I leaved simplified model version that can be milled on the simple regular 4 axis CNC mill but demands more handwork with metal (that gives brilliant final result)
Model was adapted from this model set: https://www.cgtrader.com/3d-print-models/jewelry/rings/dunlop-motorcycle-tire-rings-set
Earring dimensions are shown on the preview pictures.
