Solder fume extractor with customizable mesh

prusaprinters

This simple soldering fume extractor is meant for use with activated carbon sheet filters and a 120mm PC case fan.The model is split into three parts: Body, Top, MeshPrint 2x Mesh using a slicer modifier:Select the Mesh object from the right menu, add a modifier cylinder.Resize and position the cylinder to leave a small circle untouched on the outside of the model.Add Infill and Layers and perimeters settings on the cylinder.Set top and bottom layers to 0 and perimeters to a low value. I used 2.Set an infill pattern and density you like, see examples in the photos.Print 1x Body and Top parts. Glue a mesh piece into each. I used superglue.The mesh model was created with 0.1mm tolerance, so it should be a very snug fit.I had to sand a very small amount off still to make it fit just right. My mesh is even bulging a little bit, but I like the look. The Body and Top parts glue together with the help of registration nubs.(My printer wasn't able to reproduce the nubs as intended, so I sanded them down and ignored them.)I used a 120mm PC case fan that came with self-tapping screws, so I reused them, but any sufficiently long M4 screw with a nut should be fine to mount. The holes are countersunk so the head doesn't interfere with inserting the filter.Make sure airflow direction is correct before attaching.After assembling, slide one or two slices of the filter material through the empty side.I used two layers which still lets enough airflow to suck the fumes away from around 10cm distance. Your milage may vary depending on your fan.My fan is 12v, so I soldered it to a 12v adapter with a simple toggle switch.The switch fit nicely into the corner of the fan body, and I used some hot glue to secure the wiring and switch. It looks a bit messy, but works.
