Funnel for Rancilio Filter Baskets

thingiverse

This is a funnel to help dispense the ground coffee from one of those 'clear disposable' tumblers into the filter baskets of the Rancilio Silvia. I like to weigh my ground coffee out on some scales using the clear cup to get the exact amount. Using a funnel like this reduces the risk of spilling all the ground coffee everywhere. Just tip it upside down and shake it about and the grounds should transfer into the filter basket. As always this may not suit everybody's needs but hopefully it can provide some inspiration for your own designs. Of course your filter basket and tumbler dimensions could be a little different than mine, but I believe these things are pretty universal.
