## Summary description

JustPi brass threaded inserts for 3D printing — a kit of 50 metal inserts in various sizes for embedding strong internal threads in printed plastic parts. Designed to be heat-pressed or ultrasonic-inserted into thermoplastics to provide durable M-type threads for assemblies, fixtures, enclosures and repair jobs in hobbyist and prototyping use.

## Long description

JustPi threaded brass inserts for 3D printing are a kit of 50 metal inserts in various sizes designed to create durable internal threads in thermoplastic parts. These brass inserts are intended for installation by heat pressing or ultrasonic insertion into printed components, producing reliable M-type threads for mechanical assemblies, enclosures, fixtures and repair tasks. The kit provides a range of insert sizes to match different screw diameters and wall thicknesses commonly encountered in hobbyist and prototyping work.
Advantages
The brass construction offers good corrosion resistance, reliable dimensional stability and improved wear resistance compared with direct tapping of plastic. Inserts distribute fastening loads over a larger area of the printed part, reducing stress concentration and preventing thread stripping in softer thermoplastics. A mixed-size kit ensures flexibility across multiple projects and reduces the need to source individual sizes.
Suitable for
 Prototyping and hobby 3D-printed enclosures and parts
 Repair and retrofit of plastic components requiring strong threaded connections
 Fixtures, jigs and small mechanical assemblies made from thermoplastics
 Electronics housings requiring repeatable screw mounting points
Key specifications
 Material: brass
 Quantity: 50 pieces per kit
 Installation methods: heat press insertion, ultrasonic insertion
 Compatibility: designed for use with common thermoplastics used in FDM/FFF printing
 Function: internal M-type threaded connections for fasteners
How to use
Choose an insert size appropriate for the screw type and the thickness of the printed wall. Prepare the printed part by cleaning the insertion hole and ensuring correct diameter and depth for the chosen insert. For heat pressing, apply controlled heat to the insert using a soldering iron with an insert-tip or a dedicated heat-set tool, and press the insert straight into the hole until the flange sits flush or to the recommended depth. Allow the part to cool before applying torque. For ultrasonic insertion, follow the ultrasonic device manufacturer's instructions and use a compatible sonotrode to embed the insert into the thermoplastic. Avoid overheating the surrounding material to prevent deformation.
Usage recommendations
Use inserts in appropriately sized holes and verify thread engagement with sample pieces before final assembly. When working with thin walls, consider reinforcing the area with higher infill or a washer on the mating fastener to distribute load. Store the kit in a dry place to preserve material condition and choose installation parameters that match the specific plastic type (PLA, ABS, PETG, etc.).
