3D-printable magazine for the FN P90 platform. Includes CAD files, test data, and community-driven development. The project aims to explore printability, mechanical reliability, and material performance through open collaboration and iterative testing.

⚠️ This project is intended strictly for educational, research, and prototyping purposes. Users are responsible for ensuring compliance with all applicable local laws and regulations.

Development Status
  • Alpha Phase: Completed
    The alpha prototype has undergone successful testing focused on:

  • Feed geometry and round alignment

  • Spring retention and follower travel
  • Print tolerance and assembly fit

Results confirm consistent feed operation and structural integrity under controlled testing conditions.

  • Current Phase: Public Beta Release
    The project has entered public beta, opening access to the design files for broader community evaluation. The goal of this phase is to collect user feedback on:

  • Printability across different printers and materials

  • Long-term durability and wear resistance
  • Ease of assembly and potential tolerance adjustments
  • Overall performance consistency
Disclaimer
  • Check Local Laws: Ensure compliance with all local regulations before printing.
  • No Responsibility for Misuse: These files are for personal, non-commercial use only.
Acknowledgments

This project is made possible through collaboration between open-source designers, material engineers, and hobbyist testers. Community contributions are critical to refining and validating the design through real-world testing. big thanks to ketcham and all alpha testers for making development of this project possible.
