About this model

WhatThis is a spool insert designed for BambuLab spools, but with the step files included it can be modified/remixed for other spools as well - which I encourage anyone with the skills to do. It essentially allows the filament to be put on both halves of the spool individually, all while maintaining AMS compatibility and functionality for the loaded filament. This project doesn't allow you to use more colors than AMS allows, just to “store” more different filaments in the AMS enclosure or anywhere else.This is not limited to AMS, it should work with all kinds of rollers, spool holders, filament dryers, etc. WhyI've accumulated many spools with a little bit of filament left (
