✨ Three‑Piece Triangle Puzzle

A simple shape with a sneaky twist.

This minimalist puzzle is made from three identical pieces that fit together to form a perfect triangle. It looks easy at first glance, but the fun comes from figuring out the right orientation to make everything fit into place to make a 3 dimensional triangle.

Great as a desk fidget, a warm‑up print, or a tiny challenge to hand to friends who think they’re puzzle masters.
