I did similar as in the post # 19 https://www.elektroda.pl/rtvforum/topic3222554.html#15786057 Only a fan I put a 230V duct. The total cost is PLN 130 and a half hours of work. I have ozonized a room, a car, carpets (I have a dog), even a washing machine and the effect is amazing. I used to borrow some "traffic" for around PLN 150, it wasn't a problem.
I did it out of curiosity, if I would get rid of the bad smell. After this treatment, the washing machine smells like new. As for the drawer, you can do the reduction at the outlet to the desired diameter and attach the drawer.
