120mm fan filter

Printed on tronxy x1, with 60% filling. I used 3mm screws and at least 7mm threads on them. I also used a filter material from Aliexpress here is an approximate name (it may not be translated that way) : computer filter 500x400x3/5 mm, mesh PC, family fan, cooler, dust cover, sponge, 60PPI. The filter itself is simply attached to the suction fan, it works perfectly. There is a photo filter on my PC that has been standing for several months, I have a cat, so it gets clogged quickly with wool, the filter solved the problem of wool in the PC.
