Deterrence Dispensed (DetDisp) is a decentralized, online collective that promotes and distributes designs for open-source 3D-printed firearms, gun parts, and handloaded cartridges.
[4] In February 2019, a group of 3D gun designers chose the name "Deterrence Dispensed" as a reference to Defense Distributed, the first 3D firearms organization.
[1][3] Deterrence Dispensed has used multiple, alternative social networks and platforms due to suspensions from mainstream sites, including Tumblr and Keybase.
[4][8] In December of 2024, The Gatalog took credit for releasing the files for the printable frame and suppressor allegedly used by Luigi Mangione in the killing of UnitedHealthcare CEO Brian Thompson.
[11] At the peak of its popularity, the group also distributed blueprints for AR-15s, an AKM receiver called the "Plastikov", handgun frames, and a magazine for Glock pistols named after New Jersey Senator Bob Menendez, who once pushed for crackdowns on the online sharing of 3D-printable firearms designs.
