Big fan club

[Jack Crow]

Hi all,
More of this fan holder stuff.

At work I use a small fan for blowing away solder fumes. Let's be honest too much of that stuff is lung rot, so why inhale?

Anyhow, that fan bit the dust, one day it simply quit turning.

Left it there for a week and for no reason it started up again.
Either way I can't trust it. Time to move on.

I need to pivot this fan so that it blows the fumes off the work area, and not chill the soldering tools.

This is what I made.

It is actually five parts.
Two grills of the same design.
Two clamps that form the top part of the pivot, again the same part printed twice.
One base.

To hold the clamps together I use 8 4-40 hex cap screws with deep counter bore into the clamp body.
This is because screws I stock were shorter than what I needed. Adjust the printed part to fit the hardware.
Four on each side.
Had to hold the clamps together while tightening, as to prevent the parts from spreading.
How they hold on the flats nicely.

The big holes in the base are to lighten up the amount of plastic used.

The unit is very sturdy won't budge.

Was thinking of making a second pivot point in the base.
An option for a second unit, but not required for the current application.

The fan it's self is a 24 volt unit run at 12 volts to reduce air flow.
The grills act as flow restrictions as well.
The breeze is about right to push solder smoke away, and it is very low noise. (A major advantage for me.)

The base has holes for mounting screws. So that is how it will attach.

If I say anything more, it will sound like a late night tv ad.

Hope all is well on your end.

That's not a big fan. Checkout one.

Never knew there were a lot of world's biggest fan videos on YouTube, but not surprized

Yupp, big fan.
Mostly it will have to blow away solder fumes.
More than that is not required.
