Compact Smart Air Purifier

thingiverse

Being highly allergic, and not wanting to spend hundreds of euros for a smart filter, I decided print one. Or at least the thing surrounding the filter... The filter I used is the [Xiaomi Smart Air Purifier 4 Compact Filter ](https://www.mi.com/global/product/xiaomi-smart-air-purifier-4-compact-filter) which I think is perfect as it cost no more than 30$, and blocks basically everything. As smart module i went for the [Sonoff Basic](https://sonoff.tech/product/diy-smart-switches/basicr2/), which is a 220v remote switch compatible with Google/Alexa. A fan is needed (no air is gonna move otherwise). I choose one from AliExpress which is maybe a little too powerfull (and noisy) | [High Air Volume Fan 120mm (Type C)](https://it.aliexpress.com/item/4000163820741.html). It has the following specs: 4600RPM / 160CFM / 12V / 1.34A. Again, probably overkill for a small home filter, so choose whatever 120mm fan you like To connect the switch to the fan i choose the [Adogo transformer 60w, 12v, 5A](https://www.amazon.it/dp/B01M0GR3NN?psc=1&ref=ppx_yo2ov_dt_b_product_details). There are many other with the same dimensions/specs on both amazon and aliexpress. Below time and material to print each piece * Base ~11h 109g * Side ~ 2h 20g * Top ~11h 106g * Fan&Power ~14h 145g * Cover ~ 8h 67g Inside the Fan&Power and Cover, I have designed holders for the electronic components. I'm including also the 3mf files so you can remove/edit those in case you decide to go for other switch/transformers.
