Shape Stacking Tower

Shape Stacking Tower – Simple, Fun & Colorful

I designed this stacking toy with young kids in mind. Something simple, satisfying, and great for developing motor skills without being overwhelming.

This set includes 3 different shapes:

• Circle
• Square
• Triangle

Each shape stacks onto its own peg, helping little ones practice:

• Hand-eye coordination
• Shape recognition
• Color sorting
• Fine motor skills

It’s a classic concept, but I wanted to give it a clean, modern look that prints beautifully and feels solid in hand.

Easy & Beginner Friendly Print

This is a very easy print which makes it perfect if you're new to 3D printing.

• No AMS required
• No supports needed
• Simple geometry
• Clean layers
• Prints reliably

You can print each level in a different color like I did, or keep it all one color and let kids mix it up. Since each part is separate, color swaps are very easy, just print the layers individually.

Perfect For

• Toddlers learning shapes
• Montessori-style play
• Daycares
• Handmade gifts
• Craft fairs

It’s sturdy, simple, and satisfying to stack.

If you print it, I’d love to see your version — especially your color combinations. Feel free to leave a review and share a photo.
