3D-printed e-reader case shaped like a pistol challenges new gun-blocking software laws
Maker Luke Blackford created a 3D-printed e-reader case that looks like a handgun but cannot fire, highlighting potential false positives in proposed laws requiring 3D printers to block firearm-like objects.
A Kentucky-based creator known as Luke Blackford, or "Luke The Maker," has designed a bizarre accessory: a 3D-printed case for the Xteink X4 e-reader modeled after a real pistol frame. Dubbed the "Gundle," the device cannot shoot — squeezing the trigger does nothing. Blackford published the files on his personal website, deliberately avoiding major platforms like Thingiverse to limit distribution.
This case comes amid debates over new legislation in New York and California that would mandate gun-blocking software on all new 3D printers. The software would scan every file before printing and block those deemed to be firearms or firearm parts. New York has already passed such a law, and California's state assembly has approved it, but implementation details are left to expert panels.
Experts, including Cliff Braun of the Electronic Frontier Foundation, warn about false positives: the e-reader case, which looks gun-like but is harmless, could be blocked. Dartmouth professor Solomon Diamond explains that different detection methods — hashing, computer vision, or geometric identification — have varying risks. A visual resemblance-based system might flag the case, while geometric identification could theoretically avoid false positives.
Blackford opposes the mandates, citing open-source principles and arguing that those determined to print guns will find a way. He has not taken the case in public, fearing dangerous misunderstandings with police, as it resembles a real firearm. Federal "orange tip" laws require imitation firearms to have bright orange muzzles, but Blackford's case is an art project, not a toy.
Supporters like New York Governor Kathy Hochul argue the law is needed to curb "ghost guns" — untraceable 3D-printed firearms. The NYPD reported recovering 109 mostly 3D-printed guns in 2024, up from just one in 2021. However, critics note this is a fraction of conventional guns seized: over 5,200 illegal guns were recovered in New York City in 2025 alone. Blackford believes 3D printing guns is still too cumbersome to pose a major threat, and obtaining a real gun remains easier.
