Dust extraction adapter, 35 mm tool port to 58 mm hose
A tapered adapter that connects the small 35 mm dust port on a sander or router to the 58 mm hose of a shop vacuum, so chips end up in the bin instead of on the floor. The tool end is a 34.6 mm male spigot with a 1 degree taper, the hose end a 58.4 mm socket 40 mm deep, and a 20 mm conical section links them with 2.5 mm walls. A shallow rib on the spigot helps it stay seated under vibration; print upright in PETG for a bit of flex.
Dust ports are a jumble of near-standard sizes, and SpeakCAD sizes each end to the diameters you actually measure, including which end is male and which is female. Preview free in the browser and ask for a 90-degree elbow or a different hose size.
