Anyone has a Sketchup drawing for a servo-motor shaft adapter that can be printed

Anyone has a Sketchup drawing for a servo-motor shaft adapter that can be printed and is willing to share ?

Thanks.

@Mark_Rehorst Thanks but this looks more for a step motor. I’l looking for something for a small servo motor like this http://www.pololu.com/product/948

FYI I’m making one. I have a prototype printed already with the right dimensions for the shaft. Will be uploaded to @Thingiverse and @YouMagine soon. I’ll post here with the links when available.
