Hello everyone!! Today’s model is… the Lotto Draw Machine! 🎉✨ In Korea, “lotto” is the most common lottery system. You pick numbers from 1 to 45, and if you get the right ones, you win! 😆 This model includes numbers 1–45, so it works perfectly for Korean-style lotto. For other countries with different number ranges, only numbers up to 45 are currently included. I’ll bring a bigger number version next time! 😂 ✨ Features This draw machine uses a familiar fidget gear mechanism! It combines a ring gear, sun gear, and planet gears that spin smoothly 🔄🛠️ Then we added a roulette-like number system so you can manually draw numbers 🎯 🧩 Assembly Assembly is very simple! Just insert the pins and you’re almost done ✔️ However, the fit is intentionally tight to provide stronger fixation. So: Insert slightly → tap gently with a solid object 🔨 and the pin will seat firmly! 💡 Usage Tips If rotation feels too stiff → shorten and slightly trim the pin tips for smoother movement. Once assembled
