Air filter - for home and 3d printing

i've made this filter to reduce armfull thing produced by FDM printer like PM (particulate matter) and VOCs (organic volatile compounds). This filter reduces bad smells from the printer and common air dust too.
You can also use it without an enclosure close to a FDM printer, it will still filter the air of the room and remove bad smells and armfull things.
Or you can use it as a normal home air filter if you want, it's not made only for the 3d printing world.

Material required:
1) 8 x M3x10 mm screws; 4 x M3x5 mm screws.
2) Air filter like this:

it's a cylinder filter compatible with Xiaomi Mi air purifier 2, 2H, 2S, 3, 3H, Pro. It's an HEPA 13 filter with a carbon membrane usefull to remove PM and some VOCs.
3) Active carbon pellets:
you can choose between multiple brands and forms, just be sure that the pellets are bigger than the holes of the net in the "Carbon filter lower part". I use this brand:

4) Now you need a motor that moves the air. I use this kitchen hood:
https://www.amazon.it/dp/B0CM9FGV5P?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1
it's a 38 W engine and can move 525 m^3/h and it's enought for any enclosure.

Assembling instructions:
It's a very easy assembling.
1) first print all the parts needed. I used Creality Hyper PETG but you can use ASA or ABS if you want. Even PLA if you don't heat up your enclosure.
1) Screw the 4 Colums to the Head
2) Put the air filter over the Base
3) Screw the 4 Colums to the base while the filter is between them
4) Screw the kitchen hood to the Head
5) glue the Carbon filter upper part to the lower part with cyanoacrylate glue (fastest and easiest to use) or any other glue you want
6) put 100 to 450 g of active carbon pellets into the Carbon filter (i use 200 g)
7) close the Carbon filter with the cap then gently put it on the kitchen hood
8) set the kitchen hood on

Suggestions:
Sometimes the kitchen hood comes with a grid, you can remove it if you want with a screwdriver since it's not possible to touch the spinning fan when assembled.
i've named the parts from the lowest to the highest (1 lowest part, the base) to make the assembling easier.
