The individual builds will be pretty cheap: sub $75 with an Arduino, NEMA stepper motor, PCB, a few other parts, and some plastic enclosures.

There's definitely some bootstrapping costs to acquiring tools (3d printer, soldering set up, adjustable power supply, Fusion 360 license). That's around $1k-1500 for a nice hobbyist setup by the time you get everything.

The real cost is when you decide to quit your software job to work on a hardware project :)

That strikes me as being a much higher unit cost than I would have anticipated. Are you way overprovisioned on the arduino and the steppers or is there something else fancy going on that's driving costs up?

It could certainly be much cheaper than $75, that's just the ceiling. Arduino Nano BLE is $30 and one stepper on Amazon is $15. Plus other small hardware, plastic and assembly.
