Everlasting AMS Cardboard Spool Ring (TPU)

UPDATE: I recommend that to avoid the TPU rings from hitting the lid of the AMS and causing moisture to leak into the AMS, you should consider printing an AMS lid riser. I have found that this: https://makerworld.com/en/models/33133#profileId-266148https://makerworld.com/en/models/937393-ams-lid-riser?from=search#profileId-902476 works quite well

TPU adapter ring for all 1kg (200mm diameter) cardboard spools

• This model features a rim on two sides to secure itself tightly onto your cardboard spool
• This will last you forever (will not experience layer separation when fitting onto cardboard spool)
• Preserves your AMS rollers by offering a soft and compliant surface to roll against
• Do note that it can take a minute to fit the TPU adapter ring onto the cardboard. Once you've done it a few times it'll get easier. Stretch it as you need.
