Solder Fume Extractor with separate horizontal pin (Double knob)

thingiverse

Yes, I've had the same experience. To solve this issue, I used a 2-dollar soldering iron to drill into the foot and create a horizontally printable pin. The gap between the screw and rod is now eliminated, resulting in greater durability. At first, adjusting with the two knobs may feel uncomfortable, but you'll soon find a comfortable position. The hole size of the drilled foot remains identical to the original.
