Bản lề phẳng không chốt (Flat No-Pin Hinge)

This is a flat plastic hinge designed for use in campers, where lightweight, compact, all-plastic solutions are often needed. Unlike central-pin hinges (which are often too thick), this model has a slim profile that fits easily even in tight spaces.

🧪 I'm currently testing it in PLA, but I recommend printing in PETG for better strength and durability, especially when exposed to heat or mechanical stress.

📐 The Fusion360 source file is included, so you can easily adjust the dimensions to fit your needs.

🔧 Not comfortable with modeling or editing? No problem! If you need a specific size, feel free to message me. I'll upload a ready-to-print .stl version for you.

🛠 I'm still working on optimizing the alignment of the top layes: right now, I'm not getting two or three perfectly matching top layers. Aligning the hinge longitudinally with respect to the fold seems to offer the best compromise between flexibility and strength.

💡 Suggestions and improvements are very welcome. If you want to create a remix or adapt the project to your setup, go for it! Any feedback is helpful to make this model better and more versatile.
