Yeah, I think a resin printer should handle the detail nicely.

I hear there are less brittle resins these days, but yeah.  If the resin
is like the resin print from Shapeways, I'd even worry that a bit of
torque inserting or removing it would snap off a pin.

The sintered nylon from Shapeways, on the other hand, is tough,
only a few bucks, and minimal hassle (except for the wait).  Even
comes out in translucent white :-).

Are there another print vendors/technologies folks have had luck
with with small, finely detailed replacement parts?
