Model of an ambiguous solid.

Look at it from one direction it appears to be a cube, and from the opposite it appears to be a cylinder. Hold it up to a mirror and you see both at the same time.

The 4x model is a group of four of the shapes merged together to produce the illusion of either 4 connected cubes or four overlapping cylinders. # Print Settings Printer Brand: LulzBot Printer: TAZ 5 Supports: Yes Resolution: 0.2 Infill: 20% Notes: This was very difficult for me to print as removing the supports without damaging the print was a problem. # Post-Printing Take care when removing the support material as it is easy to split the model. # How I Designed This

After seeing this video (not my video), I had to try and model this shape.

I created a cube in Blender, subdivided the sides so I would be able to smoothly deform it. I worked from the final viewing angle and distorted the cube until it looked like a cylinder. I switched to the opposite viewing angle and made sure the object looked like a cube.
