Printbuchse - alternative connector socket for fischertechnik cables

thingiverse

The Fischertechnik construction toy system employs cables with unique 2.6mm jacks, compatible connector sockets known as "Bundhülsen" (flush sleeves) are hard to obtain, relatively expensive, and require drilling holes in your PCBs for mounting. My "Printbuchse" (printed socket) serves as a cost-effective, simple, and reliable alternative connection option for Fischertechnik jacks. It only requires 2.54mm male pin headers, and the jacks are held in place by a printed sleeve. The Printbuchse enables straightforward connectivity for boards, shields, or breadboards with male header pins. Its primary purpose is for use in PCB enclosures, which is why I include a technical drawing and a FreeCAD source file. Due to the dimensions of the Fischertechnik jacks (7x3.4mm), only every second pin of a 2.54mm pin row can be utilized. The Printbuchse comes in three versions: * Pin header adapter (STL-file): makes a pin header compatible with ft-jacks * FT-jack adapter (STL-file): makes an ft-jack compatible with male pin headers * Generic Printbuchse (FreeCAD file and technical drawing): to be used in your own designs. See this I2C port expander or this electrical distributor block for examples. If you use my design for your own developments and publish them, please add the tag "Printbuchse," so that it is easy to reference them, and link back to this page.
