Reinforced for GoPro Shoulder Strap Mount
The original idea is great! I wanted shoulder mounts for my gopro and insta360s long time and finally found the Nicrombious's one!
But I also found some stress concentration on original design so I added some pyramids at the bottom the neck by PrusaSlicer's "Add Shape -> Gallery" feature. It takes only 10 minutes.
Works perfectly and I'm very satisfied with it!
