I'm working on an acrylic box and wanted to do something different, moving away from the conventional hinges that I usually see in other projects. My inspiration was a hidden hinge used in woodworking for doors, and I decided to create a simplified version. This hinge is designed to open up to 180°, making it versatile for various applications. The model was created in Fusion360 as a parametric model, which means you can adjust the total height of the hinge and change the thickness of the pins according to your needs. The hinge worked very well and didn't break even when force was applied. I uploaded the model in Fusion 360 so you can edit it.
