Fast Strong Automatic Respooler V2 (1-3kg spools)

🌀 Fast Strong Automatic Respooler V2 (1–3 kg Spools) After several successful respooler designs, I have finally completed the version featuring a fully automatic filament guide / level-wind system! I went through numerous community reviews and feedback from my previous models, picked the best suggestions, and packed them all into this ultimate design: ✨ Key Features & Upgrades: 🎯 Fully Automatic Filament Leveling: Evenly guides and lays the filament side-to-side across the target spool with zero manual effort. 🛑 Friction Brake Screw on Donor Spool: Prevents the donor spool from freewheeling/over-spinning and creating tangles when you pause or stop rewinding. 🔩 Standard Hex Bit Drive: Replaced the dedicated drill pin with a universal hex slot — now easily driven by any standard electric screwdriver, drill bit, or the included manual crank handle. 🗜️ Anti-Lift Spool Latches & Table Mounts: Added secure spool retainers so the spools won't lift when hand-cranking, plus screw holes in the base to bolt the respooler down to your desk, shelf, or workbench.   ♻️ 100% 3D Printable (Zero Non-Printed Hardware): No bearings, metal rods, or screws needed! The only non-printed item required is a short piece of standard PTFE tube for the filament guide. 🔄 Backwards Compatible: If you’ve already printed my previous version, you only need to print the updated/diff parts! The core components remain fully compatible. 🔗 3 kg Spool Expansion Link To complete the 3 kg spool setup, print the adapter included in the files and use it with this spool holder: 👉 3kg Filament Spool Holder Extension on MakerWorld 🛠️ Hardware & Bill of Materials (BOM): 3D Printed Parts (all included in the print profiles) 1× Short piece of standard PTFE tube (approx. 3–5 cm) 🖨️ Recommended Print Settings: Material: PETG / PLA / ABS (PETG or PLA Tough recommended for gears and axles) Layer Height: 0.20 - 0.24 mm Walls / Perimeters: 2 or more Infill: 10% Gyroid Supports: Only where specified in the print profile 🙏 Credits & Attribution: A big shoutout and huge thanks to KYZ Design! Some parts, including the gear mechanism, were adapted and remixed from the fantastic PASTA lite Receiver project. Thank you for the inspiration and great engineering!   Happy printing & smooth respooling!
