Alternative Door Lock

This alternative door lock model is inspired by recent school shootings to provide an extra layer of security in schools without retrofitted latest security measures. It also serves as a portable security solution for rented rooms while traveling and keeping children away from certain rooms. The design is easy to use, with quick steps of placing the vice between end plates, shutting the door, sliding the vice sideways, pushing the rod until tight, and locking it down with a lever. An additional lock rod provides extra security. The original design fits door jams between 2.5-9 inches, but this entry showcases a 30% scale model while maintaining structural integrity by adjusting some dimensions. Made of various materials such as stainless steel for the rod and ABS plastic for other parts, the design can be 3D printed using Fused Deposition Modeling for wider accessibility.
