Solder Fume Extractor (Minimalistic)

thingiverse

Description: Lead solder emits toxic fumes. Lead-Free solder has a core that produces more toxic fumes. Choose your poison. How about less poison? There are other Solder Fume Extractors available, but I wanted something minimalistic. This extractor stands up steadily, covers the soldering area, and can stand on any side. It prints easily too. I printed the fan cover in about 1.2 hours, the back plate in about 1.4 hours, and the front box in about 2.1 hours. I printed this at 0.3 resolution, 60% infill, and 60 mm/s speed. Zeebly's design works with a helping hand. I was not able to get it to work with my helping hands, so I re-designed it. I wanted something simple that is easily printable (I believe in KISS, keep it simple stupid). So, I added a flat back cover that allows the fan to sit level. I re-designed the box area so that things overlap to form a square. I removed the helping hands attachment. Now, the unit can sit flat on any surface. Parts: 1x 120mm Computer Fan (I used a CoolMaster 12VDC, 0.16A case fan) 1x AC to 12VDC Wall Wart Adapter (must supply > .2A for my fan choice) Tools and parts to connect fan to AC Adapter 4x #6 bolt 2.5 Inches long (M4 65mm SHOULD work) 8x #6 nut (M4 nut) 2x #6 nut (M4 nut) OPTIONAL 12x #6 washer (M4 washer) 2x Activated Carbon Filter (I used Corner Biz Aquarium filters from Amazon, 1 package) Instructions: 1. Print one each of the STL files (fan cover flat, back plate with one wall, front plate with three walls). 2. Put a washer on each bolt. 3. Attach the fan cover to the bolts so that the best side faces towards the bolt head. 4. Determine the fan orientation. The front-back arrow on the fan should point towards the fan cover. 5. Slide the fan onto the bolts using the orientation from above. 6. Place the back plate over the fan with the one wall facing away from the fan. 7. Add a washer and then a nut to each bolt. This keeps the unit from falling apart when replacing the filter, and keeps the fan tight against the chassis. 8. (OPTIONAL) Screw down two bolts next to the one wall until the top of the nut is level with the top of the one wall. 9. Do not trim the foam filters - they will squish in. 10. Squish the filters into the front plate. 11. Now, squish the front plate onto the back plate with the filters facing towards the fan AND the missing wall on the front plate oriented toward the one wall on the back plate. 12. Slide a washer onto each bolt. 13. Do NOT over-tighten! Add and tighten a nut to each bolt carefully. Printing: I printed each part with a brim. A raft would also work, but I decided to use a brim. Thanks: Thanks to Zeebly for the design.
