Self Centering Bush

I designed this as a diameter reducer for a friend's telescope. The idea was to produce a self centering bush that will convert Dia 2" to Dia 1.25".
Both diameters are purposly printed tight which allows the flexible vanes to compress and apply an even self centering force all around the bore/shaft. Important in the telescope world to keep things centred and collimated.

Could also be an airless tyre design (for RC) if printed with a flexible filament

Suitable for use as a tolerance ring.
