Ridge Wallet Clone

This reverse-engineering project deconstructs the popular Ridge Wallet to understand its clever mechanical design and recreate it using 3D printing technology. The challenge lies in achieving the same slim profile, smooth sliding action, and robust construction using additive manufacturing instead of the original machined aluminum.

The project demonstrates product design thinking, tolerance analysis, and material science considerations specific to 3D printing.

The wallet design features a clever sliding mechanism with precision tolerance requirements. Key mechanisms include card retention clips, money clip integration, and the primary sliding plate mechanism. Each component was redesigned in SolidWorks with 3D printing constraints in mind.

Critical design considerations included layer orientation for strength, living hinge design for the clip, and tolerance compensation for FDM printing (typically +0.2mm clearances). The design uses minimal support structures and can be printed on standard FDM printers. Material choice settled on PLA+ for its strength and smooth surface finish.

The final 3D-printed wallet successfully replicates the core functionality of the Ridge Wallet at a fraction of the cost. The sliding mechanism operates smoothly, and card retention is secure. Weight is comparable to the aluminum original.

Print time is approximately 4 hours. The project demonstrated that functional product clones are achievable with consumer 3D printing when design principles are properly adapted.
