I have a box with all kinds of motors and just took one out that was right for the purpose. I think I salvaged it from the lens system of an old video projector. So unfortunately I cannot help you with a good source. But you could also adapt the model to a motor that you have. However, if your motor is smaller, you could also print an adapter that makes the motor fit into the bubble machine.

It's actually all M3 screws. If the holes are too small, you can use a 3mm drill to open them up a bit.
