LEGO's smooth driving ring connector, the sleeve a gearbox's driving ring slides along: three studs long, an axle cross 8 mm into each end, a Ø2.4 bore between them, four walls 7 mm across with a concave scallop between each pair, and a Ø5.52 waist over the middle stud where the lobes ramp down over 2 mm. With the four walls rounded it is 26287; with two of them flat, 6.8 mm across, 42195.
