Snowshoe for a tripod with a 8mm tube. It may be possible to scale the part to work with other sizes. It's designed for fairly dense snow, and a lightweight setup (they will come off with too much weight).

This design seems to function decently on the snow in limited testing. However, when the tripod is strapped to a backpack, the feet tend to catch on straps, which twists them around and can pull them off. I'm planning to redesigning this part to address some of these issues.
