🔑 "U & ME" Sliding Keychain – A Clever Hidden Message Design
Elevate your everyday carry with this minimalist and interactive keychain! This isn't just a static accessory; it features a smooth sliding mechanism that reveals a hidden message.

When closed, the keychain displays a bold, geometric "U". Slide the inner piece out to reveal the "& ME" extension, creating a simple yet powerful "You & Me" concept. It's the perfect quick print for couples, best friends, or anyone who loves functional 3D art.

🛠️ Print Settings (FDM Optimized)
This model was designed from the ground up for FDM printing, ensuring tight but functional tolerances for a satisfying sliding action:

No Supports Required: Designed to print flat on the bed—no messy overhangs or wasted material.
Easy Assembly: Two-part design (Sleeve + Slide) that snaps together through an internal rail.
Recommended Material: PLA for the best detail on the lettering, or PETG for extra durability.
Layer Height: 0.16mm or 0.20mm is ideal to ensure the sliding mechanism works smoothly right off the build plate.
Infill: 15-20% (Grid or Gyroid) for a lightweight yet sturdy feel.

✨ Design Highlights
Pocket-Friendly: Slim profile that won't bulk up your keychain.
Clean Aesthetic: Raised typography that catches the light and emphasizes the 3D effect.
Two-Tone Potential: Print the sleeve and the slide in contrasting colors to make the message pop!
