This fidget spinner keychain draws inspiration from the karambit knife design, providing a sleek and ergonomic shape that fits comfortably in your hand. The model is fully printable in one piece, with no assembly or bearings required. The center part rotates smoothly thanks to its print-in-place design. Whether you're looking for a unique keychain or a fun stress-relief tool, this spinner is the perfect combination of style and functionality.
This version provides multiple sizes of inner ring diameter to fit all fingers!
While clearance for spinning remains the same - 0,3mm so every printer can easily print it.
Printing tips:
- No supports required.
- Recommended layer height: 0.2 mm and lower
- Infill: +-20%
- Perimeters: 3+
Be cautious of large seam sizes, as they may fuse the bearing with the body, preventing it from spinning freely.
If the print is fused together, try lowering flow a few % lower.
