"Fully" 3D-Printed Stealth Heat Set Insert Press

New spring



we came up with a better way to constrain the spring

you will need to 3d print 1 new part and change 2 from the already printed

we have updated also the cad

Fully 3D-Printed Heat Set Insert Press

Inspired by the Stealth Press 1 Heat Set Insert Press (Legacy), this fully 3D-printed design is an accessible, affordable, and reliable alternative for makers. Leveraging a 3D-printed rail system inspired by Thingiverse Rail Design, this project eliminates the need for costly hardware while maintaining excellent functionality.

Acknowledgments

This project was inspired by the Stealth Press 1 Heat Set Insert Press (Legacy), which uses precision-engineered hardware like MGN rails. Our goal was to create a similar tool that is more affordable and fully 3D-printable, ensuring that anyone with access to a 3D printer can build it.
