Over the past day and a half I've been printing some of the Winterdale trees to see what they come out like. In the Kickstarter they have four variants and I've been cycling through them to build up a stock.
Here are two I've cleaned up. The one on the left is Wildwood while that on the right is Gnarly. There are two of each variant.
Here's another shot of the trees. They rake 2-3 hours each to print on my printer. Once painted up you can add clump foliage or you can leave them bare (undead or chaos theme)
When you print them they come with printing supports that are easily clipped off. Generally it is 2-3 minutes to clean them up.
Given a week I reckon I could easily print 30-40 up. Currently I have done 8 and that is under no time pressure.
