Carabiner, strong and functionable, print in place

Carabiner Clip – Strong & Functional (PLA/PETG Printable)DescriptionA 3D-printable carabiner clip for light-duty everyday use — perfect for attaching keychains, tags, small accessories, and for organizing cables, small tools, or hex key sets.There are no separate S/M/L files — use scaling in your slicer:S size: scale to ~66% (do not go lower; strength drops quickly)M size: 100% (uploaded size)L size: 125% or larger (for a beefier grip and higher durability)Improved latch (mechanism)The latch is redesigned for reliability:Anti-lateral shift: geometry prevents the arm from sliding sideways under load.Self-bracing negative angle: when force is applied, the latch locks against itself instead of slipping open, allowing more usable force without disengaging.Printing RecommendationsOrientation: Print flat on the bed.Walls / perimeters: ≥ 5 (recommended)Infill: 40–60% (Grid or Gyroid)Top/Bottom pattern: Concentric (better stress distribution)Layer height: 0.20 mm or finerSupports: Not requiredBrim: Optional (use if your adhesion is weak)Material: PETG (recommended) for toughness and a bit of flex. PLA is tested and works, but due to stiffness it’s more prone to damage under misuse; ABS/ASA are possible but also stiffer (less elastic than PETG).Scaling Guide (no separate files)~66% (S): compact, lightweight; do not scale below this.100% (M): default uploaded size; best overall balance.125%+ (L): larger, stronger, easier to handle (good for tool organization).Tip: after scaling, test the latch action; if fit is too tight/loose, adjust Horizontal Expansion (XY compensation) ±0.05–0.15 mm instead of full scaling.Notes & SafetyFor home/hobby use only; not for climbing, load-bearing, or safety-critical tasks.Even if a first attempt holds a large load, do not rely on it for heavy loads — misuse may cause breakage or injury.
