Unibody, Parametric Impossible Cube

Reworked @matt0852's nifty "Impossible Cube" to be a single 3D model (unibody—no fasteners required). The dimensions are all parametric, so you can scale and shrink it to your tastes. I also added a "curvy" mode, if you're into that (takes forever to render).

You can print it in the typical orientation (on face), but supports will be required, and it's tough to get them out from inside the cube. Another option is to render the model balanced on one corner. This way requires no supports at all, but bed adhesion will be a challenge. I recommend using a brim; the "curvy" profile might help as well.
