This is a modern 3D-printed reinterpretation of a classic wooden stacking toy.
The goal is simple but surprisingly challenging: combine different geometric shapes to build a complete 3×3 tower on the peg base.

Each piece has 2–4 holes and must be arranged so all 9 pegs are filled evenly across layers. The different shapes encourage spatial reasoning, logic, and creative problem solving — perfect for kids and satisfying for adults.

The soft colors give it a clean, Scandinavian-style look, but you can print it in any color combination you like.

Recommended Print Quantity (One Complete Set)

To build a full 3×3 tower (9 pegs total), I recommend printing:

• 1× Peg Base (3×3 layout)
• 2× L-Shape (4 holes)
• 4× L-Shape (3 holes)
• 4× Short Line (2 holes)
• 3× Long Line (3 holes)
• 1× Square
• 1x T-Shape

This combination allows multiple stacking solutions and balanced builds. 220 g of filament used in this configuration. 

Printing Tips

• Layer height: 0.2 mm works great
• Infill: 5% is sufficient (Use 15% for the base)
• No supports needed
• PLA recommended

Suggested Age

3+ (with supervision).
Small parts — not suitable for children under 3 years.
