About this item
- 【COMPLETE M3 INSTALLATION SET】Specifically curated for concentrated 3D printing projects, this set includes 100pcs industrial-grade M3x3x4mm threaded inserts and 2pcs precision M3 heatset adapters. It functions as the essential replenishment for makers who primarily utilize M3 hardware in their builds.
- 【DUAL M3 ADAPTERS INCLUDED】Never pause your workflow due to tool wear. This package provides two dedicated M3 heat-set installation adapters compatible with standard 900M and T18 series iron shafts, ensuring you always have a spare for consistent, professional embedding.
- 【PREMIUM ELECTROPLATED BRASS】Our M3 inserts are made of premium-grade brass with an electroplated finish for superior thermal conductivity and corrosion resistance. They ensure a clean melt into PLA, ABS, and PETG without residue.
- 【EXACT DIMENSIONS FOR DIY】As a specialized M3 thread insert kit, we provide the standardized M3x3x4mm size (Thread x OD x Length). This knurled nut set is a critical addition to your 3D printer toolkit, compatible with projects for Voron, Ender, or custom enclosures.
- 【COMPACT & PORTABLE STORAGE】All components are securely packed in a small case, making it easy to store in your 3D printing toolkit or workshop drawer. Keep your M3 essentials organized and ready for your next project.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
