print/shape with foamboard and use lost foam casting. dip in plaster of paris a few times for a smooth edge.

oh tank you, i'll try that

don't forget the sprue. and by smooth edge i mean smoother than sand will generally give you. you'll need to file with a needle file to get it to match exactly.
and you'll need to use pla and not abs. it needs something that will quickly evaporate instead of just melting.

No idea why you'd go to the trouble of casting when you could machine it?

Fuck, I could make that with a grinder and a drill press out of steel bar.
