120mm Arctic P120 to 125mm Carbon Filter

This air purifier is super SILENT

you can find the models on my Tinkercad and the STL files are shared here

print in PETG for flexibility compared to PLA

the tinkercad will let you easily adapt the pieces for other filter / hose sizes.

the files are available on MEGAsync

for assembly you'll need the M4 size screws

and a 12V DC power adapter

with or without dc-dc converter

as you can see, if light is an issue, print in black petg
