Tripod Counterweight Hook

Do you have a tripod with only a 1/4" screw on the bottom of the middle tube?
Have you had your tripod thrown over by a gush of wind because it wasn't counterweighted?

Say no more, this is for you.

With this hook you can counterweight your camera tripod by hanging your backpack, camerabag or a small weight from it. Print should take between 45 minutes and 90 minutes.
The tripod will be more stable, and you won't have to put your bag in the grass or on the floor.

It is attached using the 1/4" screw on the bottom of the tripod's middle tube.
You will need a bolt or another 1/4" screw to keep the hook in place.
