Screwy Cube

Hello! This is my first 3D model, the Screwy Cube. The idea is more or less based on linking blocks, or LEGOs, but worse in most ways :)Each block can be threaded into another block, and you can make fun little shapes in this way.Each cube (OK, not technically a cube, but approximately cubic shape), is one cubic inch in outer dimensions, minus the thread.It makes for a reasonably entertaining fidget and construction toy. I hope someone enjoys it.
