Ninjatek Cheetah TPU is a flexible filament which is a bit harder than NinjaFlex. This makes it easier and faster to print. The Sapphire blue is a little translucent and a wonderful color. However this post is more about the filament type than the color. I struggled getting a decent print from this filament. I intend to tune this print soon enough. The settings below are what I believe will work. Please use glue stick on PEI print beds to avoid damage. Cheetah is a bit pricey and comes in 500g on a plastic spool.
