The most popular downloads were stylized Glock 19 and 17 frames. Designed by user Chairmanwon , these files featured aggressive stippling, gas pedal thumb rests, and undercut trigger guards. In 2021, these were considered the "gold standard" for reliability, often lasting 800+ rounds when printed in eSun PLA+.

The 2021 iteration of DEFCAD proved that digital information is incredibly resilient. Despite aggressive attempts by governments to scrub these files from the internet, the decentralized nature of the web meant that files hosted on DEFCAD frequently mirrored across alternative protocols like IPFS, torrent networks, and private chat servers.

DEFCAD explicitly avoided hosting pre-sliced G-code. Because different 3D printers require unique temperature, speed, and support configurations, users were required to slice the CAD files themselves to ensure structural integrity and safety. defcad files repository 2021

DEFCAD was created by crypto-anarchist and gun rights activist Cody Wilson in 2013 under his organization, Defense Distributed. It was launched in response to MakerBot removing firearm-related files from its 3D-printing repository, Thingiverse.

The year was marked by a shift from open-access activism to a regulated, subscription-based model driven by legal pressure and a focus on increasingly practical DIY firearm designs.

: Critics argue that 3D printed guns pose a significant risk to public safety. They can be made without background checks or age verification, potentially putting weapons into the hands of individuals who are legally prohibited from possessing them. There are also concerns about the lack of regulation and oversight, which could lead to accidental injuries or misuse by individuals unfamiliar with firearms.

While the legal teams fought, the repository remained alive via the "Ghost DefCAD" — an unofficial API scraper. In 2021, a developer known as "Decker" released a Python script that scraped the subscription-only DefCAD site using machine accounts, reposting every new file to a torrent tracker named "The Odysee."
