Mechanical Butterfly - DIY Kit

Short Product Description

Build a beautifully engineered butterfly that flaps its wings using real cam-and-linkage mechanics! Kids explore biomimicry and motion design as they assemble gears, cams, and lightweight wings to bring this mechanical creature to life.

What’s Inside the Box

• Laser-cut wooden sheets (body, gears, cams & linkages)

• Lightweight PETG butterfly wings

• Wooden rods, connectors & dowels

• Rubber rings for motion transfer

• Crank handle

• Illustrated instruction manual

How It Works

Turning the crank rotates a cam-driven mechanism inside the butterfly’s body.
This motion:

• Converts rotation into up-and-down wing movement

• Keeps both wings flapping in smooth symmetry

• Demonstrates how real insects move using muscle and joint patterns

A simple, mesmerizing model of biomimicry in action.

What Kids Learn

• Cam & linkage motion

• Biomimicry and natural movement
