🧩 **Interlock Cube – 6-Bar Puzzle**
A clean, elegant and surprisingly challenging 3D puzzle

🔍 **Overview**
This model is inspired by the concept of frame puzzles, where bars interlock to form a compact structure.
Behind this apparent simplicity lies a true three-dimensional labyrinth, where each move either unlocks — or blocks — the next.

This “6-Bar Interlock Cube” follows exactly that logic:
the six pieces must be assembled in a very specific sequence, requiring observation, patience, and multiple attempts to understand.
The assembly is not straightforward: some pieces only fit at very precise angles, and the progression is far from linear.

👉 This model is based on frame puzzle principles and is an adaptation of the **“Six Frames”** puzzle designed by **Andrey Ustiuzhanin (2015)**, itself derived from the **Gordian Knot** concept.
It has been fully remodeled and optimized for 3D printing.

🧱 **Features**
6 independent pieces
Difficulty: ★★★★☆ (advanced)
→ Several misleading paths
→ Precise orientations required
→ Non-intuitive assembly sequence

A great challenge for mechanical puzzle lovers
Excellent test of printer accuracy
