I figured I would make a vibratory tumbler. Cost was very low and some shop time. I will be improving the design at some point but so far I have been using this thing with good success.
Here is a video of its construction.

Nice one. About a year ago I planned to build something similar but I did not think that I had a suitable motor and I built a rotary tumbler instead. I have a ton of those computer fans but it never occurred to me to use one of those.
I also have the same question as Frank S regarding balance and vibration.
My rotary tumbler is very noisy and I might revisit a vibratory version like yours.

The fan was set out of balance using a nut/bolt through one of the blades, the plate ontop is to reduce drag in the fan by blocking airflow. This thing is fairly silent. If you notice the spool was used as a spring as well. This design has 4 dampening sections. Feet/first level spool/second level spool/springs. The result is that even in a hard surface there is no resonance at all.
