The Ulm-based company Lockcard not only produces physical versions of some of its minimalist wallet products, but also offers free 3D print files for self-printing. Users can download the STL files via a dedicated page and print their own Lockcard elements – but only for private use.
The files are protected by copyright and may not be published or used commercially. According to Lockcard, infringements can lead to legal consequences, including claims for damages and exclusion from file access. Commercial licensing is currently not planned. The provider also excludes any liability for damage caused by improper use of the print data.
The idea for the lockcard was born in a student hall of residence in 2019. Initially, it was simply a desire to store keys compactly in a wallet. However, the implementation proved to be technically challenging – until the use of a 3D printer made the first prototypes possible. The resulting “keyplate” mechanism was the foundation stone for today’s wallet system.
Lockcard now manufactures its products in series production, some of which are made of aluminum. Development continues to take place in-house. The company not only uses traditional manufacturing processes, but also additive processes. A significant part of the prototype phase is carried out using FDM 3D printing. The community on social media accompanies many of these steps.
The provision of print files for end users is an example of the interface between the open design approach and corporate control.
