3.5 cm Durable Keyboard Clip -- 2

I need a replacement clip for my Dell wired keyboard that will raise the rear edge for a more comfortable typing angle. The original snapped, so I’m after a simple, functional redesign that measures exactly 3.5 cm in length and locks firmly into the keyboard’s existing slot.

Material is crucial—I want the strongest practical option. Feel free to recommend metal, a high-strength composite or a reinforced plastic if you can demonstrate comparable rigidity and long-term durability.

Deliverables
• 3D model files (STL + STEP) ready for 3-D printing or CNC machining
• A dimensioned drawing showing all critical measurements and tolerances
• Brief notes on the chosen material, including why it offers maximum strength and any print/machining tips

Acceptance
The clip must snap securely into the current socket without wobble, lift the keyboard by the intended height, and withstand normal typing pressure without flexing.
