Lasercut Triangle (or not) Puzzle

thingiverse

The original design was modified to be laser-cut rather than 3D printed. To enhance the puzzle's functionality, set the depth slightly beyond optimal focus for wider kerf. Assemble the largest piece with a triangular frame, creating a tray. For improved maneuverability, insert small handles like screws, sticks or similar items into designated holes; flipping pieces is unnecessary.
