FN 5.7x28mm PCC CC-BY-NC Remixable Sharable FN Beta FN P90 Magazine

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
