Here's a very well done Dr. Crusher custom figure with a very detailed card. The body, of course, is a repainted Tasha figure.
I don't think the head is 3D-printed, which would have been my way to go, but it's rather a redress of something else.
If I had to nitpick anything it's that the photo is obviously of Crusher from the later seasons, which you can tell by the collar of the uniform. The figure itself is a diamond uniform though.
The card itself is very detailed and very committed, with unique graphics added to the back.
I think 3D printing, as it becomes more accessible, will really open up the production of custom figures, especially now that you can build a 3D model of an actor's head and let the printer do the rest.
This particular figure, in case you're wondering, sold on eBay for not much money at all -- about the price of a Galoob Ferengi figure.
