Motorized Door Lock

thingiverse

This is a highly advanced, precision-crafted door lock inspired by The Amazing Spider Man. It employs a rack and pinion system, cleverly converting rotary motion into linear movement via a reliable servo motor. Once the extended rack slides perfectly into its designated slot within the sturdy "rack holder", it secures snugly into the screwed-in position on your door frame. A compatible 180-degree standard-sized servo motor (measuring precisely 40.8 × 20.1 × 38 mm) is an essential requirement for this project's smooth operation. The model's design is highly adaptable and accommodating of users' requests: if anyone requires modifications to fit smaller or larger motors, kindly leave a comment and I'll promptly upload revised models to ensure seamless functionality. In response to user feedback, notable updates have been implemented: The motor holder has undergone significant redesigns to enhance its strength and rectify certain modeling issues. This improvement guarantees robust performance and reduced risks of print failure. To address ongoing issues with gear printing, a chamfer was expertly removed from the gear model, ensuring trouble-free printing without supports or minor sagging problems. As a testament to this design's effectiveness, Makerbot itself has covered this innovative project in their stories: http://stories.makerbot.com/post/95939577127/locking-a-door-like-spider-man **Optimized Printing Settings** Printer Details: • Brand: MakerBot • Printer Model: Replicator 2 • Rafts: None • Supports: Yes (limited to Motor_Holder only) • Resolution: 0.25mm • Infill Percentage: 35% Filament Specifications: * eSun PLA in Bronze and Silver **Post-Printing Steps** After printing, simply remove supports from the Motor_Holder. A precision-crafted knife or similar tool can aid cleanup efforts, while M3 threads and self-tapping screws supplied with the servo motor guarantee smooth, stress-free installation. **Assembly Instructions** To bring this masterpiece to life: 1. Print each component in its designed orientation. 2. For optimal results, assign different infill percentages based on individual parts' requirements: * The Gear should have a low infill percentage (20-30%). * Motor_Holder demands high-resolution printing with high infill percentage (70-100%). * Rack printing requires moderate infill level (~50%). * Finally, rack holders must be printed at 100%. 3. Ensure the "Rack_Holder" is accurately positioned within your door frame for optimal alignment of the rack when it extends. Carefully install the rack into the Motor_Holder while considering any potential falls; you may need to create an additional plate on top of the rack if installing this system on a movable door or furniture piece. When installed, secure all components using M3 screws and precision-crafted tapping to perfectly align printer accuracy. Finish off the assembly by securing the gear to the servo motor via screws supplied with your original motor purchase.
