Bosch 14.4V battery powered solder fume extractor

I got inspired by this video, where they use a Makita battery to power it. I could not quickly find any STL files so I decided to create my own model for it around my Bosch battey from a broken power drill.I did reuse the plate that interfaces with the battery to integrate into my model.Needed hardware:1x switch (I used a round switch, about 20mm in diameter)1x 120mm PC fan1x 120mm active charcoal filter (can find bulk packs for cheap on AliExpress)1x LocLine flex adaptor for gooseneck, I used 4 segments and thought it would be enough as a handle.4-8x brass inserts4-8x screws, I used M3 fitting to my brass inserts. Used to mount filter holder to fan holderI printed the battery interface part in two half shells so that I could easily do all the wiring. Afterwards I could assemble it fairly easily and melt the parts together using a heat gun. I have uploaded the battery interface part in halves and as a whole one, feel free to comment for questions :-)Could also imagine to include a USB-C port or a battery voltage indicator in this build, this is the easiest working prototype and I enjoy using this. the 12V 0.23A fan (=2.76W) can theoretically be powered for up to 6.5h using the 18Wh Bosch battery, which is plenty!
