Dome for dive camera/ phone

thingiverse

Take photos while swimming with your cell phone, secured in a waterproof case, or use a GoPro or other waterproof camera to capture stunning underwater footage. You can position yourself above-water and simultaneously capture scenes beneath the surface, creating unique and captivating images. To create this setup, you'll need a balloon made of PE material. Search for "Clear Balloon" on Taobao to find the perfect one. When inflating the balloon, use a pump to prevent introducing excess water vapor into the balloon. Blowing it with your mouth can have unfortunate consequences.
