Auxetic Cubes // 20mm 3x3 rounded Fidget Toy

Here's the first of many auxetic structures I've been working on. These 9 connected cubes make a great little fidget toy and demonstrate auxetic structures that expand simultaneously in every direction (in 2D)!

More to come :)

Printing Guidelines

Fairly loose requirements, just make sure your printer isn't overextruding and has decent cooling so none of the parts fuse. I used 0.16mm layer height, 3 shells. No supports!
