Fume filter for 3D printers

Absorbs nasties when printing ABS.

This is a holder to allow pieces of activated carbon filter foam to be held against the inlet of a small centrifugal blower (BFB0712H). Install inside the enclosure of a 3D printer to absorb microfine particles and VOCs when printing ABS.

This is simply recirculating air within the enclosure, rather than venting outside. Since ABS needs a warm enclosure, this keeps the heat in.

You can attach the whole assembly to the inside of the enclosure with M4
