Clamp for espresso filter

thingiverse

The Krups espresso machine design features a clamp that securely holds the espresso filter cup during cleaning. This is especially useful in removing fine coffee grains that tend to obstruct holes. For safety reasons, use a high-pressure waterjet instead of your fingers. To avoid getting wet, attach the clamp and filter onto a plank, don an outdoor raincoat, and enjoy the splashing water!
