Innovative and Seamless: Automatic Filament Feeder Introducing the innovative automatic filament feeder, designed to streamline the workflow of 3D printer users. This unique design, currently compatible with the Ender 3 V2 series, will soon be adaptable to other printer models with additional adapters. Never let your production halt when filament runs out, as the automatic filament feeder seamlessly switches to a backup filament instantly. Operating without the need for any electronic components, this feeder simplifies and enhances the user experience, ensuring uninterrupted and efficient production processes. Its innovative design allows users to quickly switch to another backup filament by inserting it into the empty channel, eliminating the hassle of technical adjustments. Say goodbye to layer imperfections caused by paused prints during filament changes. With the infinite backup capability provided by the automatic filament feeder, users can save both time and money by using spare filament instead of discarding small pieces. Using it is straightforward: Simply insert the spare filament into the empty channel and detach the end of the current filament from the spool. Seamless, practical, and user-friendly: Step into a new era of production with the automatic filament feeder. #Materials: 3 pieces 4x15mm screw(or you can use glue) 4 pieces rubber 5 cm 1.5mm Copper Cable(It is used because it can be easily sanded) Links: https://youtu.be/KJn7XMqlfTE https://youtu.be/IwSQP_h1VZ0 https://youtu.be/HAmFlgkF8U8 https://youtu.be/B6rMiN1Jgts 3D PRINTING SETTINGS #All settings are available in the downloaded folder.
