Parametric Titanium Keyring Design

I need a parametric 3D model of a key-ring that will ultimately be machined or wire cut in titanium. The file must be fully editable so I can tweak dimensions, hole diameters, or add/remove text without starting from scratch. I am after a clean, moderately detailed style—something more refined than a simple washer shape but not overflowing with tiny filigree. Think sleek contours, a subtle relief logo or initials, and smooth edges suited to titanium’s strength and finish.

Solid-modelling tools such as , Solid Edge, or FreeCAD are all fine as long as the end result is parametric. Please export the final design in STEP and STL, and include a short screen-recording or annotated screenshots that show how the primary parameters can be changed (overall diameter, thickness, clearance for the split-ring, any engraved text).

Deliverables
• Editable parametric CAD file
• STEP + STL for manufacturing
• Quick guide (video or images) demonstrating parameter control
• Two basic renders that illustrate material finish and scale

I may ask later for minor adjustments or alternate metal versions (e.g., stainless steel) based on the same parameter set, so keep the model clean and well-organized.
