Note; the two different versions are not merely the model flipped 180, the cubes are in a different orientation. This alters how many of the hinges are printed vertically vs horizontally. It may print better for you in one orientation or the other. I've found that the 'flipped' version prints best and uses the least support material.

I loved the original Kobayashi thing but wasn't happy with all the pointy, sharp edges. Not so comfortable in the hand when fidgeting.

I saw someone else did a more rounded remix but even that still had lots of sharp edges. I'm just learning Fusion 360 and all the other various software involved in 3D printing so this was a fun learning experience for my first remix.

There are a couple more corners, the outer ones away from the hinges, that I'd like to get more rounded but couldn't figure out how to do in Fusion yet.

I printed at 15% inflll with tree supports from Cura
