This adapter system wraps the edges of a REPRAPPER 1kg 200x62mm cardboard spool in order to:

• provide smooth rotation within a Bambu Lab AMS
• prevent carboard debris from depositing within a Bambu Lab AMS

Features:

• Reusable
• REPRAPPER nameplate for easy identification when reusing

Instructions:

• Measure your spool first to ensure it matches the specified dimensions
• Print this model twice for a single spool
• Affix one spool ring adapter on each side of the REPRAPPER spool
• See attached photos

Considerations:

• REPRAPPER spools measure 200mm in diameter which leaves only 2mm until the AMS lid clearance limit of 202mm is reached. While the adapter diameter is still less than 202mm some people have stated their spools are rubbing against the lid with adapters attached. If you're experiencing this I would suggest either not pushing the lid all the way down into the gasket which should provide 1-2mm of additional clearance or please see my AMS Lid Riser model which allows you to keep your AMS lid closed while providing additional clearance for larger filament spools.
• Print Material: Please print with a basic PLA or PETG to minimize any shrinkage.
• Too Tight? Too Loose? Cardboard expands with humidity and contracts when dried. A cardboard spool that has absorbed too much moisture may cause the adapters to fit very tight. Placing the spool in a filament dryer, such as the SUNLU S2, for a bit should resolve this. Note, you should not dry the spool with the adapters attached as they can warp in the heat. Keep in mind that after a long drying session the adapters may fit too loose. This should resolve itself shortly as the cardboard reabsorbs some moisture from the air.
