Deodorizer Holder with Screw

Wife and I wanted this for the inside of a cloth baby diaper garbage can. I originally tried to drill the hole, myself, in the original design. It worked but since I only have "socket head cap screws," I remixed it with a pre-made hole for an M2 screw (2mm screw with 4mm diameter head). It may work with other types of screw heads.

Disclaimer: I suck at TinkerCAD so when I attempted to add an upside down cone to create the extra base for the screw, it somehow didn't 100% mesh up and left a (cool-looking, I think) pattern on the inside of the base. If someone wants to clean it up and remix it, feel free. I am definitely far from an expert!
