Butterfly Knife Trainer | Print-in-Place Fidget Toy

This print-in-place butterfly knife trainer is designed to be both a fun fidget toy and a smooth, satisfying desk accessory. Built with a fully integrated hinge system, this model prints in one piece—no assembly, no extra parts, just remove it from the build plate and start flipping.

The design focuses on clean movement and balance, making it great for casual flipping, fidgeting, or just messing around while you are at your desk. The trainer-style blade keeps it safe, while still giving you the look and feel of a real butterfly knife. The geometric cutouts in the handles not only give it a unique, modern style but also reduce weight and improve handling.

This model is perfect for anyone looking for:

• A satisfying fidget toy
• A cool print-in-place mechanism
• A desk accessory that actually feels interactive
• A safe way to practice flipping tricks

The hinge is designed to move freely if your printer is well-tuned, but may need a little break-in depending on your settings. After a few flips, it should loosen up and become even smoother.

Printing Information:

• Print-in-place (no assembly required)
• No supports needed
• Works best with a well-calibrated printer
• Recommended layer height: 0.16–0.2 mm for smoother الحركة
• Use good bed adhesion to prevent warping

Tips for best results:

• If the hinge feels tight at first, gently work it loose instead of forcing it
• Make sure your tolerances are dialed in for moving parts
• Slower print speeds can improve hinge quality

This model was designed with both function and style in mind, combining a clean look with a fun, interactive mechanism.
