Key Advantages

• Only 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, prints even faster and uses <5g of filament.

Description

This 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 grams of filament, but it is also reusable and easily attaches in the same manner as conventional adapters.

This adapter has proven to be a game-changer, eliminating the need for other AMS modifications that claim to address retraction and entanglement issues. Remarkably, I’ve found that spool weights are no longer necessary. However, as with any solution, individual results may vary. Happy printing!

Tolerances

Compared to plastic spools, cardboard spools are more vulnerable to various external factors, such as moisture, temperature fluctuations, and variations in the production process (up to +/-2mm). Consequently, you may encounter slight variations in the fit, which can range from slightly looser to tighter. In extreme cases, the spool adapter may not fit at all. In these scenarios, you can make the necessary adjustments to the model's scale using the Bambu Slicer for both the X and Y axes. Ensure that you uncheck the "uniform scale" option before proceeding. If your spool's diameter exceeds the default setting, consider increasing the scale by 1%. Conversely, if your spool's diameter is smaller, reduce the scale by 1%, and your setup should be ready for use.

Printing

When it comes to printing, you should produce two adapters for each cardboard spool. It is advisable to steer clear of materials that exhibit low friction, such as Silk-PLA, to ensure optimal performance. Most of the time I use Standard PLA.
