Trinket Box With Captive Hinge
Created today
Description
Most 3D-printed boxes rely on thin plastic living hinges that fatigue and snap off after a week of use, or require separate filament fragments as pins that eventually back out. This print-in-place trinket box uses a five-knuckle mechanical barrel hinge with integrated teardrop pins to prevent bridging collapse. A front thumb-tab with an offset detent provides a positive snap closure so the lid doesn't flap open when jostled in a drawer.
- Dimensions: 70 mm x 50 mm x 30 mm overall footprint.
- Walls: 2 mm solid perimeters for rigidity.
- Tolerances: 0.4 mm clearance inside the hinge barrel to prevent the knuckles from fusing during extrusion.
- Printing: Print fully closed, flat on the base. Requires no supports.
