# Fun Asymmetrical Round-and-Square Eyeglasses—Support-Free 3D-Printed Model
A cleverly designed pair of eyeglass frames featuring an asymmetrical combination of a round lens and a square frame, which instantly grabs attention. The all-3D-printed design incorporates filament-based hinges instead of traditional metal hardware, making it both print-friendly and easy to assemble.

## ✨ Product Highlights
1. Unique Asymmetrical Design: The frame combines a circular lens with a square frame, breaking away from the conventional symmetrical look of eyewear. This distinctive, playful design effortlessly lends itself to quirky, retro, or artistic styling.
2. Foldable Temple Design: The temples fold open and closed smoothly thanks to filament-based hinges, allowing for compact storage and portability—perfect for everyday use or travel, as they easily slip into your pocket.
3. Zero Supports, No Metal Hardware: The model has been structurally optimized so that the entire frame can be printed without additional supports, ensuring even beginners achieve successful prints on their first try. Plus, no screws or other metal components are required; the hinges are assembled using only filament, keeping costs low and assembly incredibly simple.
4. Filament-Based Hinge Design: The hinge points between the temples and the frame are pre-equipped with filament insertion holes. During assembly, simply thread the filament through these holes, leaving extra length at both ends. Heat the filament with a lighter, then press it firmly against the surface to set it in place—resulting in strong, durable connections that require no additional tools.

## 🛠️ Printing Recommendations
- Recommended Filament: PETG (high toughness, ideal for hinge structures, resistant to breakage)

## 📦 Assembly Tutorial
1. Prepare a length of filament made from the same material as your print filament, slightly longer than the combined length of the hinge holes on both sides.
2. Thread the filament through the hinge holes on the frame and temples, ensuring the temples can open and close smoothly.
3. Gently heat the excess filament at both ends with a lighter until it softens, then quickly press it onto the frame surface. Allow it to cool and harden, forming rivet-like attachment points.
4. Once the filament has fully cooled and set, the assembly is complete, and the temples can now be freely folded and unfolded.
