Description of STL - Sliding number puzzle
This is a classic-style sliding number puzzle, also known as the "15 puzzle." The model consists of 16 numbered tiles from 1 to 15, with one empty space, designed for 3D printing. The tiles are intended to slide within a base or frame, allowing the numbers to be rearranged. Printing in FDM or resin is viable, with resin recommended for a smoother and more precise finish on the tiles and base. It is a single model that requires printing separate parts for the complete set. Ideal for 3D printing beginners, as an educational toy for children to develop logic and patience, or as a nostalgic small gift for adults.
