Stepped 51/54/58 mm Espresso Dosing Funnel
This one-piece dosing funnel sits in the basket of a 51, 54 or 58 mm espresso portafilter, so grounds don't spill over the rim while you grind and distribute. It has three stepped spigots, each about 1 mm under nominal (50, 53 and 57 mm OD), joined by 45° seating cones. Whichever step fits your basket drops in, and the next cone centres the funnel on the rim. It has a 46 mm throat, a hopper 84 mm across and a total height of 40 mm.
Espresso Knock Box With 1/2 in PVC Bar
A 96 x 84 x 84 mm espresso knock box for dumping used pucks from 51–58 mm portafilters. The knock bar is a 96 mm offcut of 1/2 in schedule 40 PVC pipe (21.3 mm OD). It slides through 21.9 mm teardrop bores in thick side bosses, so you can pull it out to wash the bin or swap in a new bar.
Espresso Portafilter Tamping Stand
A counter-top tamping stand for 58 mm espresso portafilters: the basket body drops into a 60.5 mm seat with a 45° lead-in, the bayonet lugs rest on the 7 mm top plate, and the handle passes out through a 32 mm front slot with a shelf under it so nothing tips forward. The 90 x 91 x 70 mm shell is open-bottomed so drips fall straight through to your towel or drip tray, side windows let you grab the basket, and two M4 clearance holes in the rear ears let you screw it down to a shelf or bar board. 54 mm portafilters sit on their lugs the same way.
