This past Halloween I ran into a new (to me) but common failure with one of my bubble foggers. One of the plastic gears that moves the bubble arm/stem down into the bubble solution and then back up to blow out the fog broke in half. I took the unit apart and found the broken gear, but I have no idea how to find a replacement gear that would work. Here's a a couple pictures of the broken gear. Anyone have any advice on where I might get a matching or exact replacement since Gemmy doesn't sell them?
