It's a replacement drip tray that goes on the bottom of used Nespresso capsules bin for Krups Essenza Mini Coffee Machine. My wife accidentally tossed it to trash so I had to print a replacement.

Printed in ASA, but I guess PETG or even PLA should do. Yes, my ironing settings for ASA could use some calibration, but the part is invisible once in place so I'm not going to waste plastic to make it better.
