Minimalistic Solder Fume Extractor

Introduction

Minimalistic solder fume extractor with 120mm fan and two active coal filters. Easily prints in three separate parts and slides together into a space efficient and sturdy package. The bottom is fastened with two countersunk M3 screws and threaded inserts for longevity and easy filter changes.

The fan holder is designed to accept Noctuas anti-vibration mounts, which is why there is such a big counterbore. Normal fan screws or machine screws should also work. The fan holder has been updated to a v2, in order to fix tolerance issues that several people have had.

Parts list

1. 3D printed parts (I used PETG filament, PLA is also fine)
2. 120mm high airflow fan, e.g. Noctua NF-F12 industrialPPC-3000
3. 2x Active Coal Filter, e.g. RND 560-00157, from DISTRELEC
4. DC Power Jack 2.5x5.5mm, e.g. RND 205-00906, from DISTRELEC
5. DC Power Plug 2.5x5.5mm, e.g. RND 205-00901, from DISTRELEC
6. Power Rocker Switch, e.g. RND 210-00553, from DISTRELEC
7. 2x M3 Threaded inserts, e.g. RS PRO 278-534, from RS Components
8. 2x M3 x 8mm Hex Socket Countersunk Screw, e.g. RS PRO 281-388, from RS Components
9. DC Power Adapter with suitable specifications for the selected fan
10. Appropriate wire

Post-printing

1. Gather all required parts, see parts list below.
2. Brass threaded inserts are melted into the plastic using a soldering iron.
3. Insert and wire up the power plug and switch. I recommend wiring in a 3-/4 pin fan connector, rather than wiring the fan directly into the circuit. This makes it easier to change out the fan later, if it breaks or you need a higher RPM fan.
4. Attach the fan to the fan holder, using Noctua anti-vibration mounts or screws.
5. Insert the fan holder, with fan, and two active coal filter into the frame.
6. Attach bottom using two M3 countersunk screws.
7. Wire in the power plug to a DC power supply, suitable for the selected fan. 2.5x5.5mm is a fairly common DC barrel power plug, so you might already have a suitable power supply with this plug already laying around.
8. Plug in and enjoy a healthy soldering environment!
