Interactive Montessori Shape Sorter - Paintable Educational Toy

Unleash creativity and cognitive development with this unique Interactive Montessori Shape Sorter. This isn't just a 3D-printed toy; it's a shared activity designed for parents and children to engage together in learning and artistic expression. It promotes early development by enhancing geometric shape recognition, color matching skills, and fine motor coordination.

Key Features & Educational Benefits:

Ready-to-Paint Reliefs: Both the sorting base and all geometric shapes feature special recessed areas (reliefs), perfectly designed for painting. This interactive element encourages parents and children to bond while coloring the shapes with safe acrylic paints, transforming each piece into a vibrant, personalized learning tool.

Smooth & Safe Interaction: Engineered with a 2mm safety clearance between the shapes and their corresponding slots. This precise gap ensures that pieces slide in and out effortlessly, preventing frustrating jams and promoting independent play.

Durable & Print-Optimized: Crafted for robust play. The base features a technical bottom chamfer for flawless printing and stability, ensuring the toy withstands enthusiastic use.

Painting Tips:

Painting Guide: Use child-safe, non-toxic acrylic paints for coloring the recessed areas. A clear, water-based sealant can be applied after painting to protect the colors and make the toy more durable.

3D printing settings
Orientation: Print the main base and all individual geometric shapes flat on their bottom surface.

Supports: NONE. All elements, including the recessed painting areas, are optimized for support-free printing.

Material: PLA (non-toxic and available in a wide range of colors).

Layer Height: 0.2 mm (provides a good balance for details and print time).

Wall Line Count: 3 perimeters.

Infill: 15-20% (Gyroid or Grid pattern).

Flawless Base: The integrated bottom chamfer on the main base prevents "Elephant's Foot" and ensures a clean, stable bottom surface.

Precision Fit: The 2mm clearance is crucial for smooth interaction. Ensure your printer's flow rate is calibrated. If the fit is slightly off, minor adjustments to "Horizontal Expansion" (e.g., -0.05mm to -0.1mm) might be needed.
