EasyThreed K7 – 1kg Filament Spool Holder with Bearings

📌 Description This spool holder was designed specifically for the EasyThreed K7, allowing the use of standard 1kg filament spools with smooth and stable rotation. Unlike simple holders, this design uses bearings at the base, significantly reducing friction and strain on the extruder — which is especially important for lightweight printers like the K7. The system works with a fixed central axis and a rotating base supported by bearings, ensuring consistent filament feeding. ⸻ ⚙️ Features • ✔ Bearing-based system (ultra smooth rotation) • ✔ Compatible with standard 1kg spools • ✔ Reduces extruder strain • ✔ Improves print consistency • ✔ Stable base with anti-slip support • ✔ Compact and efficient design ⸻ 🔩 Required Hardware To assemble this model, you will need: • 🔹 4 small bearings (common type like 608 or similar) • 🔹 Glue (optional, depending on fit tolerance) The bearings are placed in the base and support the rotating platform. ⸻ 🖨️ Print Settings (recommended) • Material: PLA • Layer height: 0.2 mm • Infill: 20%–30% • Walls: 3 perimeters ⚠️ Supports • Required: YES • Type: Tree supports 🌳 • Density: Low to medium • Interface: Recommended for better finish 💡 Tip: Use tree supports only where necessary (internal overhangs) to save material and make removal easier. ⸻ 🧩 Assembly 1. Print all parts 2. Insert the 4 bearings into the base 3. Place the rotating platform on top of the bearings 4. Insert the central shaft 5. Place your filament spool ⸻ ⚠️ Notes • Rotation quality depends on print accuracy and bearing quality • You may need to slightly adjust tolerance depending on your printer • Works with PLA, PETG, and other materials ⸻ 💡 Extra Tip For even smoother and quieter operation: • Lightly lubricate the bearings • Add rubber feet (as shown in the photos) ⸻ 📂 Included Files • Base (with bearing slots) • Central shaft • Top support ⸻ 🙌 Support the project If you found this useful: • 👍 Like • ⭐ Favorite • 📸 Share your make
