🌞 Solar-powered educational kit | DIY science model—get hands-on with clean energy⚡

Here’s a solar‑powered windmill model perfect for students and craft enthusiasts! No complicated circuits required—experience the direct conversion of “light energy → electrical energy → mechanical energy” in an intuitive way. It makes a great desktop decoration as well as an excellent tool for introducing scientific concepts to young learners.

🛠️ Model Overview

– Designed for separate part printing: the main body, support frame, blades, and other components are printed individually, without complex supports. Even a standard home 3D printer can handle it easily, making it beginner-friendly!

– All screw holes are precisely pre‑drilled, so once printed, you can quickly assemble the parts using readily available external components. The joints fit tightly without rework, ensuring a stable structure that won’t wobble.

🧩 Essential External Components (readily available on PDD/TB)

✅ 60×60mm solar panel (a standard small size works fine; ensure the voltage matches your 130 motor)

✅ One 130 DC micro‑motor (a regular toy motor will do—it’s very affordable)

✅ Several M3×10mm and M3×20mm hex bolts plus M3 nuts (about a dozen should suffice)

✨ Highlights & Usage Ideas

– A fantastic educational tool: when exposed to sunlight or artificial light, the windmill spins automatically, vividly demonstrating the principle of solar power generation—perfect for science outreach activities or classroom demonstrations!

– Stylish yet practical: crafted from matte dark gray plastic with subtle 3D‑printed layer textures, this piece doubles as both an educational aid and a minimalist industrial‑style desk ornament.

💡 Printing & Assembly Tips

– Recommended print settings: PLA or PETG filament, layer height 0.15–0.2mm, infill 15%–20%, no supports needed; print each part separately in one go.

– Assembly tip: connect the solar panel and motor correctly according to polarity to avoid reverse connection issues that prevent rotation.
