About this 3D model

Spool adapter for the 250g R3D spools to allow them to work in the Bambu Lab AMS. Print both pieces, they thread together in the middle. This is designed to fit the cardboard spool that has an inner diameter of either 54mm or 52mm and a thickness of ~32mm. Results may vary depending on the spools you have, if you need different sizes send me a message I can create more sizes! You can also cut the models and only print the threads to test the thread fit first and adjust print settings to get the proper fit. 8 Nov 2025 Update Added step files 29 Dec 2023 Update Files labeled with 54mm have a 54mm diameter and can fit spools that have an inner diamter >54mm Files labeled 52mm have a 52mm diameter.
