The yarn goes into a 12mm aluminum tube. This connects to one end of this part. At the other end you can attach an oldham coupler (19mm diameter). See http://en.wikipedia.org/wiki/Coupling#Oldham This allows me to connect a 4mm rod at the other end for the bobin and for power transfer, which is difficult to do with a 12mm tube.<br></br><img alt="Spinningcoupler" src="http://static3.ponoko.com/design_images/images/54962/9a617e21-153a-70e5-b458-e7af0cc2e33b/spinningcoupler.stl_showroom_image.png?1336239358" /> Sat, 05 May 2012 17:51:23 GMT http://www.ponoko.com/showroom/14jERC3Z/7929?time=Sat+May+05+17%3A44%3A58+UTC+2012 14jERC3Z
