Here is a collection to customize your Sandcastles with bricks, windows, flags, shields and soldiers. More items will come to make your day in the beach a little more epic. This is just the start :)

I've used Blender to create the items and optimize it test by test to make them easy to print and unmold.

Inspired in the "CreativeTools" sand play set http://www.thingiverse.com/thing:909118
