Xiaomi/Smartmi Air Purifier activated carbon mod

I MADE A NEW VERSION WHICH IS WAY BETTER: https://www.printables.com/model/1557098-xiaomismartmi-air-purifier-activated-carbon-mod-v2

This is a mod for multiple Air Purifiers made by Xiaomi which use the SCG4026GL filter and it's variants. There are multiple designs out there, but none of them are what I wanted - so I designed this one.

You can fit this to your personal needs, if you want. Here is the Tinkercad link: https://www.tinkercad.com/things/0GAgcX8UXpE-xiaomi-air-purifier-aktivkohle-mod?sharecode=zQ2rfPsPp3Ugc-TSZZnAQ-e4ZVkbRZGnudw0X8bnHYU

Air Purifiers this mod is compatible with:

• All Xiaomi/Mi/Smartmi etc. Air Purifiers which use the SCG4026GL type of filter (normal, green and purple one).

• 2

• 2H

• 2C

• 2S

• 3

• 3C

• 3H

• Pro

• Smartmi Air Purifiers (like this one https://eu.smartmiglobal.com/products/smartmi-air-purifierhttps://eu.smartmiglobal.com/products/smartmi-air-purifier)

• And probably some more models.

NOTE: I personally tested it with the Xiaomi 3C and the Smartmi Air Purifiers.

Some facts:

• Side openings are 3,2mm, bottoms are 2mm: You can use 4mm activated carbon pellets or even granulate.

• Openings are just on the lower half of the mod, so the air is forced through most of the activated carbon pellets. This is the biggest design problem I saw on other mods.

• It uses M3 screws and heated inserts for durability.

• Option to use a filter material on top of the activated carbon if yours is a bit dusty, but this is optional.

What you need:

• 4x M3 heated inserts

• 4x M3 screws (DIN 912) with at least 7-8mm length, but they can be longer if you don't have them on hand

• Filament (PLA, PETG, ABS or whatever you want to use)

• A 3D-Printer :-)

Happy printing!
