I agree there's a wide gap between modeling and designing workable parts, but parameterized modeling mechanism is kind of out of scope for home printers. And while I guass many won't know about tolerances as intimately as professional most of the time guesswork and trials will be good enough for home appliances. It's not like everyone will build robotic arms with articulate hands as phrotesis on repraps.
