turned out nice, I'd be tempted to try to make a mold out of that.

You can make molds of models, then you can quickly, cheaply and easily cast them with a variety of agents from plaster to epoxy.
Materials needed ? A vacuum former machine and thermoform plastic [Styrene, ABS, PETG, Polycarbonate].
You can make your own or buy one

[Some 3D model makers, vectric for instance, frown on mold making for whatever reasons and actually forbid the practice to be used on their models]
So I'd advise to look for any terms [if any] wherever you got the model and abide by them.

Thanks for the idea on finishing! I have some Corian sheets that aren't the best looking colors, had never thought of painting them.

Actually, the best way to make a mold, is silicone.

Might be, I personally have not experimented much with mold making, and vac forming works for me at the moment.
I do know the silicone material is expensive enough to send me into sticker shock every time I look, and I'm guessing it would not be infinitely reusable like vac molds.

Silicone isn't all that expensive. As for infinitely reusable... I have silicone molds that have cast hundreds of times and show no wear at all. Silicone may not last forever, but if it's properly taken care of, it will last for more casts than a person would probably use it for.
Silicone is more capable of replicating detail as well. It can reproduce undercuts and very fine details and small areas that a vac mold can't get into.

Back to the topic...

Thanks Frank!
I got a 4pack from China (.25-1mmR) that Randall and Leo mentioned from SYTOOL.NET, an was WAY surprised that I loved the cut in hardwoods.
Actually reordered more .25mmR short ones and got a longer on in same radius after seeing the cuts. :)
NICE cut, and thanks again!

Was there any extra finishing of the piece after milling and before painting? With a similar bit (1/32" bn) and a smaller step over (6%), I still get very subtle but noticeable striations from the the finishing toolpath (specifically in large, non-detailed fields) ... I don't see any in your picture and I would think that your method of painting would highlight them if they were present. Perhaps my machine is not as tightly tuned as I thought.
