Solder Fume Extractor with separate horizontal pin (Double knob)

Yes, It also happened to me.
As a solution, I drilled the foot (by 2$ soldering iron) and made this horizontally printable pin.
The layer gaps between screw and rod are no longer exist in this horiz pin, adding more durability.
Adjusting with two knobs may uncomfortable at first, but quickly you will find the comfortable pose.
The drilled foot's hole size is same as the original hole.

EDIT : ..aaand it broke again. don't turn the knobs tightly.
