Sovol Zero - Bộ lọc tuần hoàn không khí (tận dụng quạt hút có sẵn)

I wanted to do as little modification as possible to the printer just to make life easier. 

This remix removes the exhaust functionality of the printer and repurposed the exhaust fan to recirculate the chamber air and filter with activated charcoal and Hepa filter.

*Same as the original model use a height modifier to 0 - 02.65 with 25% Honeycomb on the top portion  

BOM
M3x6 x4 to mount filter housing to holes that were previously used
M3x35 x2 to secure Fan
M3x4x5 heatset inserts, shorter length heatsets can be used.
Acid Free Activated Charcoal
Hepa Filter: https://www.amazon.com/dp/B0782T7L6P?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_8

I also updated this in the Printer.cfg so that the recirculating fan turns on only when the bed is at 100 degrees or higher, so you don't have to remember to turn it on.

*If updating this section in the config file, In the "Cooling" section of the "Filament" settings make sure that "Active Air Filtration" is unselected.
