Assembly

Generating a Design

Setting up the Clojure environment

Generating the design

  • Run lein repl
  • Load the file (load-file "src/dactyl_keyboard/dactyl.clj")
  • This will regenerate the things/*.scad files
  • Use OpenSCAD to open a .scad file.
  • Make changes to design, repeat load-file, OpenSCAD will watch for changes and rerender.
  • When done, use OpenSCAD to export STL files

Tips

Printing

Pregenerated STL files are available in the things/ directory.

Wiring

Masks for the flexible PCBs I used are available for the left and right side.

A very rough guide for the brave is here - It will be improved over time (TODO)!
