I collect 3D terrain. I recently purchased a "Samurai Castle" off Etsy. They come unpainted, and they are printed by people who own 3D printers. I don't want to own one because they are bulky, temperamental, and make a lot of noise. The one that we have at work is whining pretty much all day long, making a low-key electronic squeal as it moves around the bed squeezing out hot plastic. The thing's got to be kept at a precise and relatively perfect temperature, or the plastic unlatches from the bed which then causes a huge mess. Anyway, it's much easier to purchase from people willing to do all the trouble and just get the finished product from them.
Most of the terrain that I own is "Western-themed" as that is the most popular. So the items I've been purchasing off Etsy are "Japanese" flavored, and I'm going to have fun painting this castle (I'll attach pictures below). I received it yesterday in a big box and then last night I primed it. So tonight I should be able to start with the painting. I'm going to use the paint scheme of Himeji castle, which is a famous landmark in Japan.
