Steep-Shouldered Funnel for Clean, Targeted Pouring
Created today
Description
A broad-shouldered funnel with a steep cone and a long spout carrying a gothic streak: a 100 mm outside rim (84 mm inside) gathers a jug or bottle mouth, the cone narrows to a 20 mm bore, and the 35 mm spout carries the stream into the container. At 82 mm tall it stays compact, and the smooth inner cone keeps the pour clean.
Four sealed air tunnels, 3 mm across and spaced 90° apart, run inside the wall from the top rim down through the cone. At the lower end each turns inward and opens through the bore wall about 3 mm above the spout tip, so the bottom face stays solid and air can climb while liquid runs down the middle. The walls are thickened around these tunnels — about 6 mm through the cone and an 8 mm spout wall (36 mm outside, 20 mm bore) — leaving roughly 1.6 mm of material on each side of every channel. No holes pierce the inner cone, so it vents without leaking out the sides.
Four raised skulls ring the cone between the tunnels, one every 90°, re-angled to follow the slope of the cone. Each is about 19 mm wide and stands roughly 2.5 mm proud of the surface, with eye sockets, nose and teeth lines cut into the face; the fine teeth lines may print faintly on a 0.4 mm nozzle. They give the funnel a gothic edge without interrupting the pour path.
Design notes
- 100 mm outside opening, 84 mm inside — a wide catch area for jugs and bottles
- 20 mm bore in a 36 mm spout — a fast, controlled stream; check it clears the filler or jar mouth you have in mind
- 82 mm overall height
- Four internal 3 mm air tunnels, evenly spaced 90° apart, running from the top rim down to the spout bore
- Bore ports sit about 3 mm above the spout tip, keeping the bottom face solid
- Thick walls: about 6 mm through the cone, 8 mm spout wall, with roughly 1.6 mm of material beside each tunnel
- Four raised skulls, about 19 mm wide and 2.5 mm proud, set between the tunnels
- Smooth, unbroken inner cone — no side vents or bore grooves
- Short top rim and chamfered spout tip
- Prints as one piece

lid 2
A round plug-style lid for a container with a roughly 94 mm inside diameter. A 100 mm flange rests on the rim and an 8 mm deep, 93.4 mm plug drops into the bore. Fitment Fits: round containers with a bore near 94 mm. Does not fit: bores under 93.4 mm, or slip-over use on a rim. Measure before printing: the container's inside diameter. The plug is 93.4 mm, so a 94 mm bore leaves 0.3 mm per side. Details: the underside is hollowed to 87 mm, leaving a 3 mm flange top and a 3.2 mm plug wall. Overall height: 11 mm.
