Essential Oil Diffuser

My second make. Many people use peppermint oil on a cotton ball to discourage mice in their RVs. I don't know that it really works, but I like the smell of peppermint, so worth a try. What I don't like is random wads of cotton floating around so I designed a compact container to hold a 2-1/4" round cosmetic cotton pad. I came across this lovely heartflower coin design from Belssi https://www.thingiverse.com/thing:3687894 that was easy to modify into a lid that will snap on to the base. Oily cotton stays contained and doesn't transfer to items in the drawers.
