Devon Jones on Thingiverse and elsewhere has done a lot of work on Openforge a Dwarven Forge compatible set of terrain pieces. Sadly RPGs are not in my future but these dinghies will be great for Space 1889 - the shorter one is just alien enough.
Printing notes - lots of small blobs and stringing. I think I need to turn the temperature down a bit. Slic3r now has filament specific temperature settings. I am also going to re-cut at .3 or .4 layer height for a better wood effect.
