Rock tumbling media
thingiverse
These are a few simple plastic geometric shapes to use as packing in a rock tumbler. Multiply to fill your build plate, use until they die, make more. A mix of smaller and larger works well. Don't use with different grit sizes - keep a set for fine and a set for polish, etc.
