Dust collection hose adapter generator

Every tool port and every hose is a different size, and the size on the label is rarely the size you measure. Give each end the diameter you measured and say whether it slides into or over the hose; the cuff starts loose by the clearance and tightens by the taper, so the hose jams on and stays. The checks confirm the taper grips without splitting the hose, the cone between the two ends prints without supports, the bore keeps most of the smaller hose's airflow and the walls take a hose being twisted on.

How to make it

Measure the inside or outside of each hose or port with calipers, not the label.
Set both diameters, tick which ends slide inside, and set each cuff length.
Print standing on the wider end, 3 walls, no supports; if a cuff is loose, raise Taper by 0.2 mm.

Print tips

PETG or PLA, 0.2 mm layers, 3 walls, 0 to 10% infill: the part is all wall.
Stand it on its wider end; the cone leans less than 45 degrees so it needs no supports.
Ribbed and flexible hoses stretch, so they take a bigger taper than a rigid tool port.

FAQ

Which size do I type: inside or outside diameter?

The size of the surface the adapter touches. For an end that slides inside a hose, measure the hose's inside diameter; for an end that slips over a port, measure the port's outside diameter. Then tick the inside box to match.

Why is the cuff tapered?

A straight cuff is either loose or impossible to push on. A taper of about 0.8 mm over the cuff starts loose and tightens as the hose goes home, so it jams by friction and pulls off again by hand.
