I know at least one example where someone made something like this before (http://kalerator.clueboard.co/ http://kalerator.clueboard.co/), but I have no idea if

  I poked around some web searching, and it seems viable. From what I read, it does schematic and layout, using Eagle (which means you need the paid version of Eagle if your board is over 10cm in either direction). It doesn't do column wiring [based on a web post, not first-hand experience], but it gets close enough that you could probably finish by hand or with help on a forum or reddit. There were a few posts where people proposed porting it to produce KiCAD or other EDA tool output, but I didn't readily find any "I'm finished; here it is" posts along those development lines. You still need to buy the parts and solder everything up, but for one-off, that's mostly a bit tedium, so this seems doable if you're somewhat dedicated and the type to find a way around or over small obstacles. The microcontroller and firmware for something constrained like this is almost assuredly a solved problem, so I wouldn't worry much about that [though it's something you need to chase down, of course]. But you're right, there's still enough specialized knowledge that there's no real "thingiverse equivalent" (of similar community size) for PCBs.
