Karambit Knife – 20 Grams

Karambit Fidget Knife – Finger Trainer

 

A 3D-printable karambit-style finger knife designed as a smooth, satisfying fidget trainer. The finger ring gives it the classic karambit grip and spin, making it perfect as a desk toy, EDC fidget, ADHD/anxiety aid, or cosplay prop.

 

Features

• Authentic karambit silhouette with finger ring for spinning and flipping
• Tuned tolerances for a clean friction-fit assembly — no glue / no screws required
• Prints flat, supports-friendly orientation
• Works great as a single-color print or a dual-color AMS print
• Safe blunt blade — trainer/cosplay use only, not a functional weapon

Recommended print settings

• 0.2 mm layer height
• 3+ walls, 20–40% infill (heavier infill = better hand feel)
• PLA, PETG-HF or PLA-CF all work; silk filaments may need flow tuning
• Print at 100% scale; scale up ~5–10% if your printer runs slightly tight
•  

If you print one, please post a Make — it's the best way to support free models. Boosts and likes are hugely appreciated and let me keep dropping new fidget knives. Have a knife day!
