3mm Smartrap Simple Extruder

thingiverse

I found a simpler solution by modifying the Simple Extruder for the SmartRap. One problem with it is that the other design can bend under spring tension when the extruder motor gets warm, causing accuracy issues. To address this, I added an arm to the extruder that securely mounts to the motor using three screws, preventing warping. This upgraded extruder is designed to work smoothly with 3mm filament, making it easier to get high-quality prints out of your SmartRap printer.
