GRATKIT Cardboard Spool Adapter

Key AdvantagesOnly 7g of filament per ring.Compatible spool brand name impressed.Rounded contour helps with traction, avoids pullback errors and stabilizes the spool inside the AMS.Rounded contour lowers the chance of damaging plastic storage bags.Flat variant for full AMS compatibility (see tolerance and compatibility section)200mm variant in case 199mm is too tightUpdate08.03.2024: Updated the geometry for the rounded version, optimized print profiles and added 200mm variantDescriptionThis isn't merely a typical cardboard spool adapter. By decreasing its contact area by approximately 50-60% compared to standard adapters, it significantly enhances contact pressure. Consider it akin to winter tires on a car, which generally require higher pressure to minimize their contact area with the ground. Additionally, its rounded edges help stablizing the Spool inside the AMS and minimize the likelihood of damaging plastic vacuum bags. The adapter is not only lightweight, weighing a mere 7 g
