Purpose

Extension for clamping nut on a K&F Concept ball head to enable tighter clamping when using heavy equipment.

When using the ball head with a Nikon Z7 and 70-200 f/2.8 lens, I was a little concerned about whether the clamp was thight enough. It was, but next time I want to thighten a little bit more,

Sizes

The nut extension was designed for a K&F Concept ballhead BH-28L but it may suit on other sizes of the ballhed too as long as the outsinde diameter of the clamping measures 18 mm.
Please leave a comment if using the model/part for another size of K&F ballheads.

If you need it for another size feel free to modify the provided FreeCAD file, but please publish it too - thanks.
