Trash Can with gravity swing

Modern swing lid for household and office waste bins, designed specifically for 3D printing.
The flap opens with a light push and automatically returns to the closed position using a balanced gravity mechanism — no magnets, no springs, no extra hardware.

The hinge system is fully print-in-place and integrated into the lid.
The flap is printed separately and slides onto the built-in pivot shaft.
Assembly is tool-free and takes a few seconds.

This model is optimized for functional everyday use and performs smoothly thanks to proper clearances, balancing mass and integrated rotation stops.

Works well for kitchen, bathroom, office, workshop or makerspace bins.
