Rim Ø 42 mm

The 42 mm diameter is exactly as specified, so it fits perfectly into my build without any wobble. Machining looks clean and the Standard option feels solid for the price.

Snapped this onto my son's construction kit and it fit the axle perfectly, no wobble at all. The 42 mm size matches the old one I was replacing, which saved me a headache trying to guess measurements. Nice to find a spare part that just works.

The 42 mm diameter was exactly what I needed to finish my little gear assembly, and the fit was spot on. Machining looks clean too, no burrs or rough edges out of the package.
