Raspberry Pi Camera Mount Ball Joint with Tension screw

thingiverse

So, I think 3Dkarma's Raspberry Pi ball/swivel model is a real game-changer, but getting the ball mount on the end to firmly grasp the camera housing ball was a major challenge for me. Even trying a smaller print size wasn't enough; over time it would slowly start to sag while capturing timelapses. To solve this issue, I added some tabs with holes in them that accept a 3mm bolt and nut to add extra tension to that final section. Now, the camera stays perfectly still!
