What’s it good for?
How to do it?
Attach the two clamp pieces around the neck of the tripod, and bolt them together tightly enough that they don’t slip.
Put the m8 nuts in the slots on the clamp pieces, slide the main piece over the clamps, line it all up, and insert the m8 bolts. Tighten by hand. Add more pvc tubing to make a handle. Add weight at the bottom of the tripod to keep the tripod vertical, even when moving.
