My hummingbird arrived! I did some sanding and polishing, I'm amazed at the level of detail that was able to come thru in this print. https://www.shapeways.com/model/190112/tribal_hummingbird_pen dant.html
Yes, I used a dremel with various grinding and sanding attachments, and kept increasing the grit count gradually until I was able to get a nice shine. I end up ultimately using 2000 grit sandpaper.
@ana: It would be nice in silver, I can't afford it though, especially with import fees and UPS fees. You're welcome to buy one though!
