Enhance your 3D prints with our high-quality M3 Threaded Inserts for 3D Printer Parts! **Seamless Integration:** These M3 threaded nuts can be easily inserted into 3D printer parts from Anycubic or Prusa using heat or ultrasonic methods. Simply use a soldering iron or ultrasonic tool to embed the threaded sleeves into a pre-drilled hole. **Secure & Stable Hold:** Thanks to the unique geometry of the threaded sleeve, it fits perfectly into the printer part. The opposing spiral knurled nuts provide high and balanced tightening and loosening torque, ensuring a strong clamping force for reliable connections. **Durable & Corrosion-Resistant:** Crafted from high-quality brass, these internally threaded inserts offer excellent corrosion resistance and optimal thermal conductivity. Each insert nut is designed for easy, long-lasting use. **Versatile Compatibility:** These threaded inserts are specifically designed for thermoplastics, ensuring a secure hold in materials like PLA, PETG, ABS, PPS, and PP. As the plastic around the brass sleeve cools and hardens, the insert becomes firmly anchored. **Convenient Set:** This M3x5.7 threaded insert set includes 100 pieces of M3 internal threaded inserts, each with a length of 5.7 mm, providing ample supply for your 3D printing projects.
