Clay Stamp Roller Spacer

Ian Brown (https://www.thingiverse.com/DocCopemys/about) made a couple of cool rollers for clay or cookie dough.

Darwin "Endless Forms" Clay Roller and Handle

The Vitruvian Man roller fits on the Darwin handle, but it is shorter. The spacer here (if you print two copies) will fill the gap in the handle and keep the roller centered.
