thingiverse

Achieve 3D printer autonomy by incorporating an Automatic Print Ejector into your machine. This mechanism will physically remove the printed part from the bed once printing is complete, a feature that earned it the nickname "punching machine". To witness its functionality, simply watch the provided video above. To access the detailed component list and assembly instructions for this device, visit http://www.matterhackers.com/store/digital-designs/automatic-print-ejector-the-punching-machine. This comprehensive guide is brought to you by the experienced engineers at MatterHackers. The Automatic Print Ejector offers printers unparalleled autonomy, empowering them to remove finished parts from the bed without requiring human interaction. Observe its efficiency in action at this link: https://www.youtube.com/watch?v=Viy928RLsdU Print Recommendations: MatterHackers' Pro Series PLA was utilized for printing all components (available here http://www.matterhackers.com/store/3d-printer-filament?t=1.75mm%20PRO%20Series%20PLA). For optimal results, use the following print settings: layer height of 0.2 mm and 30% infill.
