Create 3D Printable STL for Flat Toki Hat Keychain

Description: I need a skilled 3D modeler to design a clean, ready-to-print STL file for a flat Toki hat. Instead of a hat itself we are giving out keychain of the hat that we’ll be giving out at a cultural fair to teach students about different cultures Details: Shape: Simple rounded flat skullcap / Toki hat (Viking-style or Central Asian topi, (IMAGE ATTACHED) commonly worn in places like Tajikistan) Size: Approximately 30mm in diameter (about the size of a US half-dollar coin) Thickness: Good durability for a keychain (around 2-3mm thick) Features: Built-in loop/hole for attaching a keyring on one edge Border: Herringbone-style trim pattern around the edge — make it slightly raised (or a distinct layer) so I can easily change its color in my slicer software for multi-color printing Requirements: Fully support-free design (print flat on the bed), optimized for easy 3D printing, and fully scalable in slicers Deliverables: One clean, single STL file that slices well. Quick turnaround preferred.
