This is a small test object that you can use for testing out the new ironing function

Print instructions

As I don't know which filament you will use it's hard to say.

My settings for TPU:
For my test I have adapted the line width from the standard 0.45mm to 0.40. And I have chosen to leave the part cooling fan on 50%. Temperature 230°C, Bed: 50°C

As the top parts are quite small you should take care not to print to fast.
