Measuring Cup Set with Screw-On Funnel

Six US measuring cups and one funnel that screws onto every one of them. Pour popcorn kernels, rice or sugar straight from the bag without chasing them across the counter.

How it works

Every cup has the same threaded collar at the top. The funnel screws on in about a turn and a half and stops on a seat, so it sits square and nothing gets past the joint. Its throat is 43 mm, small enough to feed the 1/4 cup and wide enough that kernels pour freely into the 1 cup.

Fill until the kernels reach the bottom of the funnel, unscrew it, and level the cup with a knife. The top of the collar is flat and flush with the rim, so the knife has something to ride on. Anything left in the funnel is more than your measure.

True US sizes

Each cup is sized to the US measure at the brim, and every label shows both units: 1 cup (237 ml), 3/4 cup (177 ml), 2/3 cup (158 ml), 1/2 cup (118 ml), 1/3 cup (79 ml) and 1/4 cup (59 ml).

Printing - No supports. The cups print upright. The funnel prints mouth-down, and the files are already oriented that way. - The labels are a two-colour inlay: body in filament 1, lettering in filament 2. The 3MF uses white and black Bambu PLA Matte on an H2D with a 0.4 nozzle and 0.2 mm layers, with all six cups on plate 1 and the funnel on plate 2. - Printing in one colour? Use the STLs. The lettering is recessed 0.6 mm, so it still reads. - Plate 1 needs a 325 x 320 bed. On a smaller printer, print the parts one at a time from the STLs: each cup is 135 to 149 mm long including the handle, and the funnel is 158 mm across. - The thread has 0.4 mm of clearance, which suits a calibrated printer. If the funnel binds, check your flow first.

Use and care

Printed parts have layer lines, so these are best for dry ingredients like kernels, rice, flour and sugar. Hand wash in warm water. PLA will warp in a dishwasher; print them in PETG if you want something tougher.
