I also needed a suitable hose system to build my solder fume extraction system.
After a little trial and error, I decided to use the standard exhaust air hoses. These are actually used to transport the exhaust air from extractor hoods or dryers.
For the solder fume extraction system I decided to use a 125mm and an 80mm exhaust hose. These are connected with a 3D printed coupler.
A 3D printed funnel is then connected to the 80mm exhaust hose. The vapors produced during soldering can then be extracted via this. So that the funnel can be aligned and is stable, there is also a holder on which the tripod can be clamped.
The structure of the suction hose is described in the following article.
Safety instructions
I know the following hints are always a bit annoying and seem unnecessary. But unfortunately, many people who knew it "better" from carelessness lost their eyes, fingers or other things or hurt themselves. In comparison, a loss of data is almost not worth mentioning, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Even the coolest project is worth no injury or other annoyance. https://www.nerdiy.de/en/sicherheitshinweise/

Collect the parts you need
Before you can start building, you should first collect all the parts you need.

You need the following parts for the assembly.
- 125mm hose in the desired length
- 80mm hose in the desired length
- 6-8x cable ties
- 3D printed funnel
- 3D printed coupling adapter
You can find the STL files for printing under the following link. If you get an error while importing into your slicer, you should download the complete repository. When downloading the individual STL files, GitHub often only provides the HTML file for previewing the STL file and not the STL file itself.
Information about printing: I printed all components with 30% infill and 5 perimeters made of PLA.
Attach the hose adapter
The hose adapter enables a 125mm exhaust hose to be connected to an 80mm exhaust hose.
Mount the intake funnel
In this step, the 3D printed intake funnel is connected to the 80mm exhaust hose.

The suction funnel is mounted in the same way as the hose adapter.
Insert the suction funnel into the 80mm suction hose as shown and fix it with cable ties.
Mount the tripod adapter
The tripod adapter can be mounted on the intake funnel. In this way, the mini-tripod linked in the material list can be coupled with the intake funnel and easily set up / positioned.

For the further construction you need the following parts:
- the previously installed exhaust air hose
- the tripod adapter
- 2x M3 thread inserts
- 2x M3x10 cylinder head screws

In order to be able to mount the tripod holder, you first have to drill the mounting holes in the suction funnel.

To do this, place the tripod holder in the desired position and drill through the tripod holder into the suction funnel with a 3mm drill.
Combination with a 3D printed butterfly valve
The 125mm exhaust air hose can now be connected directly to an extraction system. Alternatively, it can also be connected to a 3D printed butterfly valve first and then connected to another suction system. If the 3D printed butterfly valve is integrated into the exhaust air hose , the suction can be controlled independently of the exhaust air system.
You can find information about the structure of the 3D printed butterfly valve in the following article.

Have fun with the project
I hope everything worked as described. If not or you have any other questions or suggestions, please let me know in the comments. Also, ideas for new projects are always welcome. 🙂
P.S. Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you appreciate that I share this information with you, I would be happy about a small donation to the coffee box. 🙂
