This is a small Japanese "hirajiro" plains castle from the sengoku period. Castle bases were simply made of earth so for the castle to survive the vagaries of weather and earth quakes, superstructures had to be light. Hence we see simple walls, small houses and open-work towers. The model is meant for use when wargaming, and will be suitable for campaigns in Japan in the 1400s and 1500s - I will use it for the Kawanakajima campaigns.I have made it for use with 10mm wargaming armies, though it would work equally well for larger or smaller scales. The ashigaru figure I placed in the courtyard for scale is 10mm foot to eye. He is a ripoff of Erik's excellent bride and groom from http://www.thingiverse.com/thing:3495 (and he's based on the bride, no less!).The model is fully parametric - change the variable "man" (for man height) in line 1 of the .scad, recompile and everything should be fine - people with 25mm or 15mm wargaming armies are not out of luck ;) Some printers probably can't do the hollow base so I uploaded an .stl with a solid base. The towers migh be a problem also; these can be commented out from the "bygg_alt()" module in the end of the .scad file. You probably don't want to actually print the ashigaru - he used to be a good bride but is now a very cheap ashigaru - but he's easy to remove from the .scad, and two of the .stl's don't have him.I'm looking at making a Makerbot-printable version, plus cleaning up some openScad code. Partway done, will be posted here when it's finished.
