Locking Reusable Spool with Markers

IMPORTANT:I highly recommend using the Bambu Cool Plate Super Tack or similar build plate, and not a textured PEI sheet for printing the spool. Because of the thin walls and numerous start lines, I had poor results and bad first layer adhesion with a textured plate. UPDATE 3/12/25:Added marker chips for 85A and 90A modifiers._______________________This reusable spool is designed to work with Bambu Lab refills and disassembled cardboard spools. AMS and AMS lite compatible, and features a locking mechanism in the core to prevent accidental loosening of the threads.You will start to feel resistance before the spool locks and there will be about a 5mm gap. Keep turning (Approx. 180 degrees) and the spool will lock and the gap will close. (If there is too much resistance, you may need to apply lubricant to the retaining ring. See note at end) Included are a set of filament identification markers that snap into the open hexagons on the sides of the spool, and sit flush to prevent snags. They
