Safe Lock

For this project, I designed and created a portable stall lock using 3D printing. The device is designed to attach to a restroom stall door and add an extra layer of security if the original lock is broken or weak. The lock works by clamping onto the door and using a tightening mechanism to hold the door closed. I chose to make this device because many public restroom stalls have unreliable locks, which can make people feel uncomfortable or worried about their privacy. By creating a simple and portable solution, this invention helps provide a more secure and private experience for users.

We used Tinkercad to design a basic bathroom stall lock. Our design is similar to a normal stall lock, but we added a built-in clamp on the back. This clamp lets the lock attach securely to the stall door without needing screws or permanent installation. The clamp grips the door so the lock can latch and keep the door closed, making it useful if the original stall lock is broken or missing.

We then printed our prototype using our 3d printers. In our first few prototypes, the screw would not fit in the hole but eventually we figured it out.

Once we were done with the base design we moved on to finishing touches. We realized that the clamp attaching to the door was too small so we made it much longer. We also added a metal circle at the end of the screw to increase it's surface area and to get it to an easier hold.
