3/8 inch is almost 10mm

An interesting observation for Radical RC parts, which are based around 10mm arms... 3/8 inch basswood sticks from the art supply store are a pretty good fill-in if you need some arms in a pinch.

It's not a super-snug fit, but I think it could work pretty well if glued or shimmed.
