   - 1x 12v USB booster cable: https://www.jaycar.com.au/universal-usb-12v-step-up-power-cable/p/PP1978./ Ensure you get the 12v version as these do come in 9v also and that wont work.
   - 1x HEPA H13 filter: https://www.bunnings.com.au/powerfit-h13-hepa-cartridge-filter_p6210793. Ensure you get this exact filter as the housing is dimensioned to fit over the end. Other filters with the same diameter may work, but are untested. This filter comes with an end-piece that will be the base of your device, so ensure this is in the box.
   - 1x USB power bank. Any power bank that can supply 5v >1amp will work but for best results choose one at least 10,000maH that supports pass-through charging. This allows you to use the battery as a UPS for the air purifier and run it continuously from a mains power, with  the battery being used for power outages.
-  - 1x 3D printed fan housing. The STL file can be found in:

   - 4pin fan cable: https://www.pccasegear.com/products/35666/cablemod-4-pin-fan-to-3x-4-pin-fan-y-cable-black-30cm. This cable is cheap and gives you three female plugs so you can make multiple devices with the one cable.
   - Heatshrink tubing 8mm (30mm long).
   - 4x rubber fan screws: https://www.pccasegear.com/products/34741/noctua-black-chromax-anti-vibration-mounting-bolts-20-pack. These unfortunately only come in a pack of 20, so you may find them in smaller amounts at other outlets. Alternatively you can use 4mm screw heat bolts and nuts, you will need to check the length you need depending on the thickness of your fan. For the fans I linked above you would need 30mm bolts.
