Ender 3 Pro Flexible Filament Attachments

After experiencing problems with the stock Ender 3 Pro's TPU filament getting stuck and not extruding, I discovered a helpful tube and bracket that aligns the filament path, reducing resistance as it approaches the hot end. The tube is secured by a small piece of cut-up raft, which I recommend printing to ensure proper tension. This simple modification has greatly improved my 3D printing experience with TPU. While the bracket didn't have a significant impact on my prints, it was an essential test piece that led me to try the more effective tube solution. When printing TPU in Cura, consider using these notable settings: * Infill: Set at 100% * Hot End Temperature: Adjust to 220C for optimal results with your specific type of TPU * Bed Temperature: Maintain a consistent 70C * Print Speed: Optimize at 30 mm/s for smooth extrusion * Retraction: Disable this feature to prevent TPU jamming * Fan Speed: Run the fan at 60% to promote even cooling Additionally, ensuring adequate build plate adhesion is crucial. In my case, applying glue stick provided a reliable solution.
