(Coffee) Grounds Keeper

A coffee grounds keeper! It keeps coffee grounds from spilling on your benchtop.

This is just a simple little thing I made for a mate.

He had been annoyed that coffee grounds would spill over the edge of the portafilter basket (yes, that's what it's called, though most people probably call it "a filter handle and that thingy you put the coffee into"), and make a mess.

He was very happy with it and uses it all the time now, so I figured it was worth sharing, despite its simplicity.

The photos should make it pretty obvious how it's used, if it's not apparent from appearances. Basically you...

- stick the grounds keeper on the portafilter basket,
- fill it up as usual to where the "conical" profile ends, which should give you the right level
- remove the grounds keeper
- tamp down the grounds and get on with making your morning brew!

I'd recommend printing in a dark material as the coffee grounds will gradually stain the plastic, even with regular washing. Perso
