18650 Holder is from Janus Pannonius here on printables. I have merged a single holder into a 3 x holder for this model.
Ball and socket chain links with hole through by StefanHH over on thingiverse. I have beefed these up a bit for the project and made the grip a bit tighter.
After countless hours of work I now see this build is very similar to the Solder Fan Fume Extractor by petrepa here on printables.
Everything else is my own modelling using SketchUp.
This build uses the following parts:
80mm PC fan. Mine happened to be the 4 wire type so I can control the fan speed and limit the noise when required.
4 pcs 1w Cool White Strip Lamp DC 3V LED on Chip. Ebay for a couple of $
1pcs 12V 30A Heavy Duty Rocker Toggle Switches from Ebay. Overkill for the build but they look good.
12VDC PWM Speed Controller for 4 wire PC fans .Ali express or Bangood.
18650 battery terminals. spring and flats. Ebay or others.
loads of wires
1 very low value resistor 100 Ohm or so
Build method (guidance only)
Print all the parts using whatever layer height you want to use and at least 4 layers top and bottom and 2 walls for a bit of strength.
Use support where it is recommended although it should only be on the Solder Fan frame claw bit.
When printing the Solder Fan Base Lower and Upper part I used pretty sparse infill and paused the print just before the top layers so I could fill the base with sand to add some weight. remember to turn the fan OFF for the top layers otherwise the sand will blow all over the printer.
Glue the Solder Fan Base Lower and Upper together.
Fit the battery terminals to the Solder Fan Battery holder and wire up to make a 12V battery pack.
Cut the connector off the 4 wire fan and solder on some extensions as the stock cable will be too short and the connector will not fit through the holes of the stand.
Solder short wires on to the LEDs so they are all in series and solder on the longer wires to get down to the base.
Hot glue the LED lights around the beveled edge and feed the wires through the holes.
Pull the fan wires through the holes and hot glue the fan in place.
Pull the wires through the ball and claw clips. I changed the ball clip design after printing so my photos will not match the model exactly…
Pull the wires into the base and snap everything together.
Wire the LED lights to the rocker switch
Wire the 4 pin fan to the PWM speed controller. New crimps will be required.
Wire the battery pack onto the rocker switch and PWM controller and test.
I included a very low value resistor in the LED circuit. The 1W LEDs are incredibly bright otherwise.
Hot glue the battery pack into the base away from the switches.
Load it up with 18650 batteries.
Snap on the battery lid and you should be good to go.
There is no filtration or anything with this it just moves the fumes away from your face.
