Destructable wall building blocks and castle pieces

thingiverse

This is a very versatile and loose fitting stacking wall block that bears similarity in concept to the popular toys available on the market. It can be stacked to form various structures such as walls, pyramids, buildings, or other similar edifices. The main difference between these blocks and others lies in their design, which allows them to be loose fitting so that when hit with any projectile, they fall or crumble spectacularly. Originally conceived as part of a larger game where you build structures and then destroy them using catapults, ball shooters, crossbows, or other common shooting toys like nerf blasters. This set does not come with figures but there are plenty of excellent figures available from other designers on Thingiverse that can be used in conjunction with this product. You can see the wall block in action in the latter part of a catapult video (go to the 28 second mark) at https://www.youtube.com/watch?v=CklUVxsG96A&t=28s. Also, it is used in a pistol crossbow video available at https://www.youtube.com/watch?v=ycw-g1T3Mnk. The wall block design utilizes OpenSCAD software to easily output .stl files of different sizes or with various features. The easiest version is the file "wall_block.scad" where you will only need to find the line "size = 2;" toward the top and change this to the desired size, which can be 1, 2, 4, 6, or 8. The subsequent lines, base_width, base_height, and curve_size, can also be modified if you want to change the scale but then you will likely need to adjust the hole heights to keep the blocks stackable with minimal effort. The file "wall_block_half.scad" has more features such as the ability to make 2-to-1 blocks for building tapers into the wall or making bricks with flat tops. Update 12/22/2019 - I added a few variants specifically designed for building castle-type structures, including wall_block_front_parapet.scad which generates a top-block with a flat top and a front castle wall that figures can "hide" behind. Square_tower_top.scad is used to generate a square tower top where figures can stand on. Unlike the wall blocks, these require some minimal infill to print, a good starting point is cubic infill at 5%. Also, square_tower_top prints best at 45 degrees infill angle rather than 0 degrees.
