Realistic 3D Orchid Flower Pendant STL Design

I need a high-detail 3D STL file of an orchid flower that I will then manufacture in .925 silver.

Key details:
Type: Pendant on collar
Design style: Realistic orchid with fine petal texture and organic curvature
Dimensions: Orchid size estimated at 1’’ 3/4 high, 2’’1/4 BUT this can be changed to get the right proportional shape
No gemstones or stone settings – pure silver piece (collar will be in stainless steel)
Finish: Suitable for polishing after casting, with crisp detail retained
File requirements: STL format, watertight, ready for 3D printing in wax/resin for casting
Manufacturing notes: Minimum wall thickness 1 mm, edges slightly rounded to avoid sharpness in final piece
Reference material: I will provide photographs of the orchid for accuracy

Important:
The model must be accurate in millimeters and optimized for small-scale jewelry production
The design should be sculpted to hold detail even after metal polishing
Please include:
Portfolio of similar organic or jewelry-scale models
