Thank you again to Will Green for his excellent base!

I print it sideways with supports to ensure that the layer lines are perpendicular to how this is inserted into the croc.
Printed with default .2 speed settings, add a color change around layer 11 / 2.20mm
use CA glue or 3D Gloop! to bond the charm to the base.
The author marked this model as their own original creation.
