Another shopping-cart innovator was Orla Watson who invented the swinging rear door to allow for “nesting” in 1946. years later, the operated locking mechanisms arrived with the only aims to destroy all freedom opportunities for the trolley society.
STLF is an actionists movement, consisting in to make copies and reproductions of lock devices from SHOPPING CARTS (the key), through 3D modeling and exporting it in standard format as (.stl) for free downloading on the Web. The user can download the file and print it out physically in 3D and contribute to the cause.
¡¡¡We want to liberate the supermarket trolleys from the chains that bind them to the capitalism!!!
From STLF we want make patent our disagreement with this oppressor device (operated locking mechanisms) and we want to provide them with a tool to help in their liberation.
HELP THE CAUSE!!!! Download 3D model here .stl
