Swiss Cheese Cube - an Optical Illusion That Is Impossible to Print

All I wanted was to make something that looks cool, that was easy to create but was impossible to print. So here is the swiss cheese cube! The design is basic, a cube with 9 holes on each of its side.

Step 1: Can You Print It?

With a perfectly balanced printer that has good retraction, I think it would be possible to print this without support, but mine isn't capable of...

Step 2: If You Want to Try...

The STL files to print this bad boy (and a smaller 3x3 holes one) are on Thingiverse, try to do it and show me your failure (or succes)!

    I thought you said with 9 holes on each side, but this design I see has 25 holes on each side, is there a reason for this discrepancy?

    Yes you are right. On the thingiverse link, I made two version of this cube and I messed up my description. One has 25 holes per side and the smaller one has 9 holes per side. The one on the picture is the big one (100mmx100mmx100mm)


    Fun design. Perhaps it would be possible to print it in multiple larger parts and then glued together.
