## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well just use the right tools
*by D***N on June 15, 2025*

A soldering iron tip is not enough, you need a proper insertion tool to keep it straight while pressing into plastic. If the iron is too hot it will float/drift so practice on scraps first.

### ⭐⭐⭐⭐⭐ Threaded Inserts: A Game-Changer for 3D Printed Projects
*by R***B on January 20, 2025*

I recently incorporated threaded inserts into my 3D printing workflow, and I'm impressed with the results. Previously, I struggled with the fragility of directly tapping threads into 3D printed parts, often leading to stripping or cracking.These heat-set inserts have completely transformed how I approach assembly. They provide reliable threads that can withstand repeated assembly and removal. The installation process is relatively straightforward, although some practice is required to achieve consistent results.Key Benefits:Increased Strength: Inserts significantly enhance the strength and durability of threaded connections in 3D printed parts.Reduced Risk of Damage: Eliminates the risk of stripping or cracking threads in the fragile 3D printed material.Versatility: Suitable for a wide range of 3D printing materials, including PLA, ABS, and even more demanding materials like nylon.Improved Aesthetics: Inserts provide a cleaner and more professional finish compared to directly tapped threads.Recommendations:Proper Selection: Choose the correct insert size and material for your specific application.Consistent Heating: Ensure even and controlled heating during installation to prevent damage to the part.Practice: Practice the installation process on scrap parts to develop the necessary technique.Overall:I highly recommend the use of threaded inserts for anyone serious about 3D printing. They offer a significant improvement in both the strength and reliability of threaded connections, making your projects more durable and professional.You will need the right tool to use them, but they are cheap and readily available.

### ⭐⭐⭐⭐⭐ Upgrade your 3D printed devices to the next level!
*by T***L on January 18, 2025*

Ever want upgrade your 3D printed devices to the next level? These can help immensely. Place you smooth end of the nut into your 3D printed screw hole.
