Hexagon Puzzle/六角益智拼圖

thingiverse

I recently stumbled upon an educational toy at a sightseeing factory that sparked an idea in me. I decided to try making one myself to see how it would turn out. At first glance, it seemed like a simple combination of geometric patterns, but as I started working on it, I realized that it was much more challenging than I initially thought. Usually, only one or two pieces can be combined together, and the rest don't quite fit. What looked like a simple puzzle actually turned out to be a frustrating challenge that required a lot of time and effort to complete. After spending hours trying to solve it, I began to wonder if my IQ was lower than I thought.
