DerBard: Ergonomic split mechanical keyboard

thingiverse

**DerBard** An ergonomic split 65 key keyboard with inbuilt palmrests, backwards tilt and per-key RGB lighting **License: CC BY-NC-SA** For personal non-commercial use. I would love to see some hobbyists get some use from this, if not just inspiration. If you're good with injection moulding, flexible PCB design or own a company that makes unusual keyboards, let me know. **Blog post** https://www.heuristic42.com/blog/55/derbard-custom-split-mechanical-keyboard-prototype/ **Related posts** https://www.heuristic42.com/blog/54/microsoft-natural-ergonomic-4000-replacement/ https://www.heuristic42.com/blog/56/anatomy-of-a-custom-keyboard/ https://www.heuristic42.com/blog/57/matching-complex-shapes-for-a-custom-keyboard-in-fusion360/ **Printing** While these files are the ones I printed on my old CR10, it's no easy task. The left half of the keyboard is much too wide to be comfortable, so this should be considered a work in progress. I was able to fix the design for the right half. If you do print it, take care to reduce support density and increase X/Y distance. The main boards are two layers printed together and must be very carefully pried apart. Wiring and soldering is incredibly fiddly. There's no good definitions, only a few drawings I did in gimp. I also fixed and worked around design mistakes while putting it together. **Software** https://github.com/pknowles/qmk_firmware/tree/derbard/keyboards/derbard
