HighStrength Fully 3DPrinted Utility Folding Knife
Print Profile(2)
Description
This project aims to create a fully 3D-printed folding utility knife focused on maximizing structural durability while maintaining print accessibility. Core objectives include:
Zero hardware integration (100% printed components)
Positive blade locking mechanism in deployed position
Update Log: Minor modifications made to the model for compatibility with larger blades (3MF files updated).
you can reprint these two components to accommodate larger blades.

Print Specifications:
3 components require supports (strategically placed for easy removal)
Default 0.2mm layer height recommended
Assembly Notice:
⚠️ Moderate complexity – Detailed video tutorial provided.
⚠️ Mandatory pre-assembly video review required.
⚠️ Maintain safe finger clearance during operation.
⚠️ Mandatory: Review the full assembly video prior to blade disassembly. Dedicated disassembly instructions are provided in the video's concluding segment.
⚠️ Disassembly Complexity Alert:
The blade retention system's high interfacial adhesion renders disassembly 150% more challenging than installation procedures.
If you require convenient blade replacement, I have other designs better suited for that purpose. This utility knife prioritizes structural strength, resulting in relatively challenging assembly and more difficult blade installation/removal. The design aims to maximize blade fixation security while addressing 3D printing's inherent Z-axis weakness by employing multiple components to fully encapsulate the blade—eliminating reliance on Z-axis layer adhesion for load-bearing. This omnidirectional constraint system necessitates complex blade handling. Different design objectives demand distinct priorities: This project focuses on hardware-free blade retention (no bolts/golden pins) through mechanical encapsulation, with intentional compromise on blade installation accessibility to achieve structural robustness.

The strength of 3D-printed knives cannot be guaranteed and they are suitable only for light-duty tasks, such as cutting paper or opening Amazon packages. Unless otherwise specified, all of my knife designs are intended for light-duty use only.
