FlexFold Wallet

FlexFold Wallet — screw less, single‑piece 3D printed wallet

A minimalist, Ridge‑style card holder that needs only printed parts plus elastic bands. No screws, no glue, no sandwich plates. Just a cleverly shaped print and two bands that lock in by wedges and friction. Built for easy printing, quick assembly, and real daily use.

Uses only ~20 grams of filament, making it lightweight and quick to print.

What it is

FlexFold Wallet is a compact card holder inspired by popular modular wallets, redesigned to be truly 3d printed and hardware‑free. It works with common Ridge‑style accessories and keeps your setup simple

Printing requirements

• Material: PETG recommended for durability

• Layer height: 0.15–0.20 mm

• Infill: 100% for maximum rigidity

• Support: Usually none needed. If your printer struggles with bridging then minimal support is needed

Elastic band requirements

• Larger Band: Minimum length of 175 millimeters

• Smaller Band: Minimum length of 70 millimeters

• Adjust the length of the bands if you prefer to carry fewer or more items.

Assembly Instructions

• Cutting the Slots:

  • Larger Band: Measure and cut 8mm slots approximately 6 millimeters from each end of the band.

  • Smaller Band: Measure and cut 8mm slots approximately 7 millimeters from each end of the band.

• Placing the Bands:

  • Larger Band: Begin by threading the larger band through the designated holes or slits on the wallet as show in the below pics. These holes are precisely sized to create a friction fit, ensuring the band stays securely in place.

    

  • Smaller Band: After the larger band is in place, thread the smaller band through the bottom holes and secure it onto the corresponding wedges.

    

  • Finally fold the two sides and bring the larger band to the opposite side where we have slot for it
