Living Hinges: Flexibility by Design 📦

A living hinge is a thin, flexible section that lets two parts bend - all printed as one piece!

Design Rules

For Flexible Filaments (TPU)

• Thickness: 0.4-0.8mm
• Can bend 180°+ repeatedly

For Rigid Filaments (PLA/PETG)

• Thickness: 0.2-0.4mm
• Works for single-bend applications
• May fatigue with repeated use

Patterns That Work

Print Orientation

Critical: Print hinge line perpendicular to layer lines!
