Combination Padlock

3D Printable 3-Digit Combination Padlock 

This is the upgraded version of the former padlock design! It is more secure, with ZERO loopholes for finding out the code (Except testing each one of course), it is smaller (around the size of a regular padlock) and generally looks more professional. Enjoy!

Elevate your security with this innovative 3D printable 3-digit combination padlock, specifically designed to offer both style and functionality. This padlock isn’t just a tool for locking; it’s a project for enthusiasts who appreciate the blend of technology with craftsmanship. Crafted for durability, this lock can be printed using robust materials like PLA or ABS, ensuring longevity and resilience against daily wear and tear.

Design Features:

Material: Optimized for printing with strong, reliable filaments like PLA or ABS, ensuring the lock’s durability and resistance to environmental factors.

Dimensions: Compact yet robust, this padlock is sized perfectly for securing lockers, backpacks, toolboxes, or any small storage space where a traditional lock might be too bulky.

Combination Mechanism: This padlock features a sophisticated 3-digit combination lock, with each dial displaying numbers from 1 to 9. This configuration provides 729 unique combinations (9 x 9 x 9), offering a good level of security for personal use.

Security: The combination lock mechanism ensures that only those who know the code can unlock it, adding a layer of security without the need for keys which can be lost or duplicated. Also, there are numerous false-gates, preventing people from easily finding out the code.

Finish: The padlock boasts a smooth finish that not only looks modern and sleek but also feels comfortable in hand. 

Usage Scenarios:

Ideal for a variety of applications, this padlock can secure your gym locker, keep your personal items safe in a shared space, or protect your tools in a workshop. Whether you’re a hobbyist or someone looking for a unique security solution, this padlock offers both practical use and a sense of personal achievement from creating it yourself.

Printing and Assembly:

The design is user-friendly for those with access to a 3D printer, with detailed instructions provided for assembly post-printing. The components are designed to fit together seamlessly, ensuring that even first-time printers can achieve a functional and attractive result. However, I recommend the following settings; at least for the K1C:

Filament: PLA

Printing temp: 220C for the nozzle, and 65 for the bed.

Speed: 300mm/s

Supports: Organic Tree - 30 Threshold

Brim: No
