It really looks similar to your knob but i did not reuse any parts of your clamp.
All parts are new designed in a result of progressive design from feedback.
In fact the knob is not part of this featured design.
So if it makes you happy i simply delete the old picture.
Btw. i wonder how you got so many likes for something not printable.
There is only one Make and it complains about missing space between
the screw and bolt. Why you didn't react on this long time ago?
