Tube Connection - Tube Based Camera Rig

I bought a Blackmagic pocket cinema camera but I was having a lot of issues keeping it steady.
This was my first attempt, I like the other one better but I was amazed at how well the 3d printed corners worked, could be used for other projects.
Uses 25.4mm tubing.

I tried a comparing type video but all it really tells is I still need to practice more.
