BUSHING HEAT PRESS INSERT TIP M3 M4

These M3 & M4 heat press insert tips are a fantastic option for 3D printing with thermoplastics.

When the tip is heated and placed in the threaded brass inserts, the surrounding plastic softens and forms around it, creating a strong, secure bond.

This keeps the insert firmly in place and strengthens the surrounding material, making the threaded connection more durable and resistant to pull-out compared to other insert types.
