The SpringFactory from HW Enterprises revisits a concept which has not seen development since early 2020 - the home manufacture of magazine springs. This printable tooling allows you to bend piano wire into rectangular springs using a single moving rotary part. The factory can be easily adjusted for different coil dimensions. The coil rise is determined by installing a printed slope which can be swapped out to change the rise. The parts included in the data package are designed for a specific diameter wire (1.3mm) but even this can be customized by modifying the included STEP files. Documentation is included to explain how to print, assemble, calibrate and use the factory. This  project is the first of several planned iterations in spring bending technology, and was motivated to help reduce the community’s reliance on commercial spring designs and the limitations this places on magazine development. Home builders can now design magazines with spring dimensions totally different from what is available commercially!
