3-bit Mechanical Punch Card Reader

3-bit Mechanical Punch Card Reader is a downloadable 3D printable model for printer parts. Review the files, license, and creator attribution before printing.

Original creator description

This is a proof-of-concept, 3-bit Jacquard-style, all-mechanical punch card reader. The design was inspired by designs in a textbook called "The Mechanism of Weaving" by T.W. Fox (it's about 100 years old, but I found a copy on Amazon), and adapted to work within the limitations of my Makerbot ToM printer. It is a single-cylinder, single-acting, positive-action device. This design could readily be adapted to a higher number of 'bits' (needles) by re-designing only a few parts. With minor modifications, it should be suitable to mounting over a miniature loom, with the bottom eyes of the hooks lifting healds or warp threads directly. This is probably as impractical as it sounds. This hosted file keeps creator credit and license details.
