So, I printed and painted a huge version of one of the miniature spaceships from one of my favorite board games. Check it out here: http://imgur.com/a/tgpNL
Most of the pics show the smaller original from the game alongside so you can see the scale. It's 400% bigger! It came out quite good, but my retraction was off a little so there are some zits all over it where the end of each layer was. I've since corrected that setting, but I'm still really happy with the print. It had a whole mess of supports due to the funky geometry. I printed it nose-up.
Oh yeah, layer height was 0.25mm, 45mm/sec print speed, at 200 degrees in white Excelvan PLA from ebay, and 20% infill in fast honeycomb via Simplify3D printed on stock metal baseplate with Elmer's EXtreme gluestick.
