RX1R II Thumb Grip

I bought a Sony RX1R II. It's a tiny powerhouse of a camera. However, it's so small that it sometimes feels a little precarious in my hands. I found that companies make thumb grips for this camera (and many others like the Fuji X100). They cost anywhere from $30 on Aliexpress, to like $150 on BH Photo…. So, I decided to make one and see if I could solve this problem on my own.

I've tested this with PLA, ASA, and PC. I ended up using Polymaker PolyMax PC. It provided the best combination of strength and rigidity. It works with the others, but I didn't spend a ton of time tinkering with infill types to see if I could get them to feel quite the same.
