PANCHROMA Bambu Lab AMS Cardboard Spool Adapter Ring

DISCLAIMER:

• New PANCHROMA spools may be smaller in diameter! Please measure your spool before printing and compare to the dimensions specified below!

• PANCHROMA spools have a larger diameter (~201mm) than most 1kg filament spools. With the adapters attached PANCHROMA spools are larger than the stock AMS lid clearance diameter of 202mm. Please see my AMS Lid Riser model which allows you to keep your AMS lid closed while providing additional clearance for larger filament spools.

Description:

This adapter system wraps the edges of a Polymaker PANCHROMA 1kg 201x66mm 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

• PANCHROMA nameplate for easy identification when reusing

Instructions:

• Print Panchroma.A and test BOTH SIDES of the PANCHROMA spool to see if it fits snug. If the ring is too loose for either side then print Panchroma.B and test again. In my case Panchroma.A fit onto the left-hand side of the spool that's plain cardboard and Panchroma.B fit onto the right-hand side with the colorful label.

• See attached photos

Considerations:

• 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.
