Best Mini Motor and Materials for DIY Electronic Butterfly in a Jar Project

I have recently grown a big interest to the old butterfly in a jar toys we would see at Lowes, Home Depot, and I wanted to try and recreate it myself.

Here's an old thread regarding the toy:

So, it looks like the toy is just a butterfly cat toy attached to some type of motor that is glued to the lid of a mason jar. Pretty e-z. I'm just trying to figure out the perfect substrate I can use to make the piece that attaches to the lid. And what motor would be good, and if anyone knows any links of mini motors I can attach a wire to. Thanks guys!

 

Not what you're looking for. But you can get a rough idea from here: https://www.youtube.com/watch?v=-cWRHEAavIU

For the substrate, you can use a thin piece of plastic, such as acrylic or polycarbonate, or even cardboard.
