Geometric Shape Sorter | Montessori Stacking Toy

🧠 Unlock the power of learning through play.

This Geometric Shape Sorter is a classic Montessori-inspired educational tool designed to help toddlers and preschoolers develop fine motor skills, shape recognition, and early counting abilities.

Unlike simple stacking toys, this puzzle introduces logic: each shape corresponds to a specific number of pegs. The child must match the holes in the shape to the correct peg configuration on the base, reinforcing the connection between geometry and numbers.

🔶 Shapes & Sorting Logic

- Circle: 1 Hole (Concept of One / Center).

- Rectangle: 2 Holes (Linear alignment).

- Triangle: 3 Holes (Corners).

- Square: 4 Holes (Symmetry).

- Hexagon: 6 Holes (Complex patterning).

🗃️ Files Included

- STl

- Bambu Studio .3mf

- Creality Print .3mf

🧩 How to Play

1. Remove all blocks from the base.

2. Encourage the child to sort the blocks by shape or color.

3. Challenge them to stack the shapes onto the correct pegs by counting the holes.

⚙️ Printing Settings

- Layer Height: 0.2mm (Standard resolution provides a smooth top surface).

- Wall Loops: 3 loops (Essential for the pegs to withstand pulling and stacking).

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

- Support: None Required. All parts are designed to print flat without supports.

- Orientation: Print the base and all shape blocks flat on the build plate.

- Material: PLA or PETG. (Use multiple colors for the shapes to create a rainbow sorting experience!).
