Ladybug ring
thingiverse
A simple two piece ring. 18.5 mm diameter Outside in red PLA Inside in black SemiFlex (NinjaFlex) Instructions Print the inside with some kind of flexible filament. I used the new SemiFlex from Fenner Drives but any flexible will work. If printed with plain PLA, try softening the inside with boiled water to make it easier to fit through the inside of the red piece.
