TERTIAL Fume Extractor & Lamp

I was often missing a work light at my workbench, and i have never used a fume extractor when i solder stuff(which is bad i think). So i thought i could kill two birds with one stone by sticking a old 120mm pc fan, an activated carbon filter and some white LED's on a TERTIAL lamp arm from Ikea and call it a day.

I ended up with a model that i think is fairly versatile and you should be able to make this your self relatively easily. Assuming you can reuse old parts laying around, this fume extractor is also relatively cheap and quick to make.
 

To build this, you would need the following parts:

1. The Ikea TERTIAL lamp, only the arm part is needed

2. A 120mm pc fan, you'll need to cut it to size to make it fit the model

3. A 130x130x10mm activated carbon filter, again you'll have to cut it slightly

4. LED's of choice, ideally running of the same voltage as the fan, i used some random 12V white ones i had

5. Some way to power everything, i bought a 12V PSU

6. 8 Pcs of 6x2.5mm round magnets, these are used to attach the LED diffuser to the Fan&Filter mount, which allows for quick and easy filter replacement

7. 2-5 Pcs of M3 5*4mm heatset inserts, at least two are needed to attach the model to the TERTIAL lamp, 3 can be used to attach the fan, but in my case, the fan is press fit

8. Some wires and basic electronics tools

9. Potentially some glue for the magnets

To make the product a little more polished and usable, you should also have:

1. An assortment of connectors to improve the disassembly and reparability

2. Some type of switches to have more control over power to the fan and the led's individually

To print the models: 

You can pretty much use whatever print settings you would prefer. The model wont be under much stress, so it should be fine to prioritize looks rather than strength when printing these. 
It's worth mentioning however, that the first layer setting on the LED diffuser can have an impact on the level/type of diffusion you get. Furthermore this part can be slightly delicate. I originally designed the diffusion layer to be 0.2mm thick, which i think is strong enough, but mine broke when i dropped it on the ground (stupid), so I've included a version that is 0.4mm thick. I haven't testet this version though, so let me know if you experience any problems with this part breaking.

Some tips for assembly:

1. Reuse the wire in the TERTIAL lamp to power the fume extractor, by just cutting off the ends and solder on your own connectors

1,5. (Very optional) Leave on the on/off switch of the TERTIAL for even more control options

2. The Fan&Filter mount has a grove on the inside around where the fan will be, this can be used for wire management

3. If you would like the LED diffuser to be fully detachable, drill out the wire hole and one of the mounting holes on the fan to 6mm, which lets you fit a little 2 pin DuPont connector through here.

I have kept assembly description relatively vague, cause i am sure there are plenty of ways to make this way better than what i did. But if people are interested, i would happily make an Instructables detailing exactly what i did :)

Also, if any dimensions aren't exactly right for you, or what ever else you have in mind, i have included the step files to hopefully allow you to remix the files. I'll also gladly add the FreeCAD files if anyone is interested. And you can of course also let me know about any other problems or anything you would like my help or advice for.
