Fume Extractor (easy build)
thingiverse
I know, yet another fume extractor. I didn't need any carbon filter and wanted to have a simple build with only few components: - 120mm fan (two ball bearings) https://www.aliexpress.com/item/1005002404506907.html - Battery capacity indicator module (1-8s blue) https://www.aliexpress.com/item/32851338868.html - 18650 lithium battery (here: spare one from a Dyson) - 20mm on-off switch https://www.aliexpress.com/item/4000899454626.html - Brass hot melt insets M3 https://www.aliexpress.com/item/1005003130163366.html - Step up charging module https://www.aliexpress.com/item/1005002817529224.html - M3 bolts 30mm The space for the 18650 battery is nicely large - glue some foam into the holder to give the battery a tight fit. Use some hot glue for the capacity indicator. Nice and strong extracting - I use it always when soldering. Charging is super easy via micro USB port.
