Cute Photo Frame Keychain 💌
A compact and creative Cute Photo Frame Keychain featuring a hidden sliding photo mechanism inside an envelope-inspired design. Carry your favorite memory everywhere with a keychain that looks simple on the outside but reveals a personal photo inside.
The keychain includes a built-in sliding frame system:
Slide the inner frame out to reveal the photo
Compact envelope-style exterior
Smooth and satisfying sliding action
Secure locking system on both ends
The mechanism is intentionally tight at first to help keep the frame securely in place.
🔒 Locking Mechanism Details
The top locking section may feel difficult to press during the first few uses
Once inserted, the frame can slide freely
A second locking point at the bottom keeps the frame secure during everyday use
⚠ After approximately 5–10 initial slides, the mechanism naturally becomes smoother and easier to operate while still remaining secure.
🖼 Photo Size
Designed for photos sized:
75 × 42 mm
Trim the photo accurately for the best fit and sliding performance.
❤ Assembly Note
A separate heart-shaped piece is included as part of the design.
The heart piece must be glued manually into the center section after printing.
