Brass Insert Nut Kit | M2–M4 Heat-Set | 3D Printer Accessory

Give your 3D prints real threads. These knurled brass insert nuts melt cleanly into PLA, ABS, and other plastics with a soldering iron, turning printed parts into assemblies you can bolt and unbolt again and again.

Features:

• Knurled brass inserts that grip plastic firmly once heat-set
• Sizes from M2 through M4 for small electronics and detailed parts
• Implant with a standard soldering iron using the included heat-set tips
• Ideal for 3D printed enclosures, e-bike accessories, and DIY repairs

Configuration: Choose a complete kit with soldering iron in your preferred insert size and piece count, or grab the no-iron set if you already have an iron and just need the inserts and tips.

Pickup available in Etobicoke; Canada Post shipping available when ordered online.
