Bambu Spool Lock

Bambu Spool Lock This is a simple but super effective lock that slides into the center of your spool and prevents it from cracking. Reusable spools (especially the Bambu ones) can get weak over time, so I designed this to stop breaks before they happen. One tiny print can literally save an entire roll of filament! FEATURES: • AMS / AMS Lite friendly — works perfectly with both • Super strong design despite being lightweight • Uses only ~1 gram of filament • 5-minute print on most machines • Easy to install and remove • Keeps your spool from flexing and splitting ASSEMBLY: Just slide the lock into the center of your spool, exactly like shown in the demo video. No tools. No hardware. It just fits and works. PRINTING INSTRUCTIONS: • Use 0.28 mm layer height for extra strength • PETG recommended for the best durability • PLA also works fine if that’s what you have • No supports needed
