After I made the wonderful Marble Machine #3 by Tulio Laanen (https://www.thingiverse.com/thing:1385312 ) I liked the idea of making an electric motor for it. Of all the things I've done so far, I liked Brannnt's project the most (https://www.thingiverse.com/thing:5357447) . However, having done it, I discovered that my gear motor is not attached to its housing and falls through it.
I had to completely redo the design by making a gear motor mount. For one power supply, it was converted to two AAA batteries that are more acceptable to me.

Additional parts required for assembly:
1pc mini gear motor GA12-N20 3v 30rpm.
