How i made it...
-Can opened a 6 inch milo tin with a can opener at both ends
-Cut a 6 inch circle through the bottom of a 5 gal bucket
-Inserted the Milo tin through the hole and sealed with hot glue
-Painstakingly made a 6 inch wire cylinder (using 1cm x 1cm square mesh i got from bunnings (or "homo depot" if you're american)
-Hot glued a layer of this kinda airy cloth kinda shit to the outside of the cylinder
-Painstakingly made an 8 inch wire mesh cylinder, with it's inside covered with the cloth that i mentioned b4. Hot glued to bucket around the other cylinder
-Filled between cylinders with carbon/charcoal (the shit that literally eats up the smell particles from the air that travels through a bunch of it)
-Sealed the top of the in-bucket filter
-'Thread' duct onto milo tin at bottom
-Cut hole and duct taped length of duct to lid, sealed lid
and HEY HEY!!
