AutoLock Stopper – 3D Printed Smart Door Stop with Automatic Locking Function

The AutoLock Stopper is a uniquely designed 3D printed door stopper that combines practicality with innovation. Unlike traditional stoppers, this model features an automatic locking mechanism that securely holds the door in place once pushed back. To release, you can simply pull the door firmly or apply light foot pressure on the stopper, making it both user-friendly and highly efficient.

This product was designed with universal compatibility, meaning it works with almost any door type and floor surface. Thanks to its clever geometry, it does not require additional parts or complex installation. For extra stability, you may optionally secure it with a small piece of double-sided tape, but in most cases, this is not necessary.

One of the biggest advantages of this design is that it is support-free, meaning the model can be printed without the need for additional structures, saving both material and print time. The part was successfully printed on a Creality Ender 3 V2 using PLA material, completing in approximately 2 hours with only a small amount of filament.

The stopper’s flexible yet sturdy construction ensures long-term durability while maintaining ease of use. Its automatic lock-and-release system makes it far more convenient compared to traditional wedges or rubber door stoppers.
