Description

Some people like the smell of solder but it's usually a good idea to avoid breathing it if you can, this will help you do so.

This is genius, thanks for sharing. Now I don't have to make my own! I printed it, and used a switch with a battery and can just flip the on off switch. Why pay 60 dollars when you can make your own!
SLAPS MY HEAD! Thanks. I have a whole tub of old wall warts hanging around.
Just a random wall wart I had lying around. Probably from an old router or something like that.

Instructions

Besides the printed parts you'll need a fan, filters and a few screws and nuts. I designed this to use a standard 120mm PC fan which I think most people have laying around. The filters I used had these dimensions: 130 x 130 x 10 mm and I stacked three of them together. I bought my carbon filters at [Conrad](http://www.conrad.com/ce/en/product/588546/), but I'm sure you can find them elsewhere as well.
.
The cross thing is optional and can be used to prevent the filters from moving back too far. I found I didn't need it though.
.
The front of the head has a lip. I included this in case you wanted to design something to go infront of the filters, for whatever reason. I first thought about attaching a flexible hose to the front but decided against it (didn't need it really).

What are you using for a power source?

Anyway you can scale this down to 80mm pc fan size? my I2 just cant print this the mouth of this thing is huge.
Perhaps you can try to print it at 0.67 scale? I might go in and change all the measurements for an 80mm but don't hold your breath, I think it will be a bit of a pain to do.
Thats fine, I was just curious if its to much of a paint ill just play around with it and see if i cant get it to work.
I printed the front head piece yesterday. Took quite a bit longer than I thought and I needed to sleep so I cut it short at about ~80-90% of the way through at around 3AM. Took about ~8 hours to get to that point and had probably another hour or two to go. The result is that my head doesn't have any lip up front at all, but I think it will still work fine.

I'm going to also try using some cuttable carbon filter pads for an aquarium that I can get from my local PetLand for $9. Just gotta print the stand and wait for my fan to arrive from deal extreme.

Definately the largest thing I've tried printing yet on my Prusa Mendel.
No problems slicing or loading this in pronterface.

I printed it with 0.3mm layer height, PLA, 15% infill, 2 perimeters.
Yeah it'll work fine without the lip. I just added that in case someone wanted to attach something to the front to keep the filters in place. I didn't find it was really needed though. If needed you could drill holes in the four corners and stretch some wire in a cross shape in the front to keep the filters in place.
What plastic did you print this in? I tried with abs and the shrinkage was insane. The whole filter holder was unusable.
I'm only set up for PLA so that's what I used.
Great Idea and Thing :)

added a frame to slide into the front for holding my filter...

will publish it on my profile after this post.

have fun.
This may be a stupid question, but how do you power your PC fan?
There are no stupid questions. PC fans normally run on 12V. In my case I use an old PC power supply because my fan happens to have a standard molex plug but you could use any type of "wall wart" you might have that gives out 12V DC. It could be from an old charger/radio/modem or whatever. Just check the label and see if it gives out the correct voltage. You can get away with lower voltage but the fan will run slower. If the voltage is too low it simply will not turn, you might see it jerk a bit though.

The red wire will be your positive and the black is your negative. Your wall wart will have markings on it which show what part of the plug is positive and which is negative so hook it up accordingly.
Wow, slicing the head resulted in a gcode over half a million lines long, and pronterface can't handle it. Just hangs when I hit print. I like the design, but really having a hard time getting it to print.
Well... yeah, it's pretty huge :D I get the same kind of code size but I didn't have any trouble printing it and I used Pronterface as well. Not really sure what to do about it I'm afraid. Maybe try older/newer versions of Pronterface or try another program entirely? Sorry I couldn't be of more help, hopefully someone else will have an idea.
Tried again and now it works for some reason. Will take 14 hours to print though, so will start it another day, so it doesn't finish at 3 in the morning ;)
Nice, good to hear :) My print took 11 hours, didn't sleep well that night... hehe. Also, please post a pic if you finish it, I'd love to see it.
Unfortunately while printing the foot, the extruder motor hit the threaded rods after 8 hours of printing because of the sheer height of the print, so 122 grams of PLA wasted :/ should have measured it beforehand. What did you print yours on?
Aww man, sorry to hear that. I printed mine on an Ultimaker. If you still want to have a go at it I could probably cut the foot in two and add a few guide pins so you could glue them together? How much height do you have to work with?
Nice man! I like it!
Awesome!
How long before the carbon filter needs to be replaced?
No idea I'm afraid. I'm guessing how much dust you have in the air, how much and how often you solder, the type of filter you use and all manner of things would play a big role. Maybe it would be a good idea to have a look at commercial products and see what they recommend? My guess is that it lasts for a pretty long time for hobby use though :)

Oh and I wouldn't trust that just a simple carbon fiber filter would catch all the nasties, you'd probably need a couple different types of filters for that. But, at the very least it gets the fumes away from your face and it should catch some of the nasties. I find it smells less at least, so it's gotta be doing something good :D
