@Frank_Herrmann Thanks for sharing the links. I printed the parts yesterday. But I found a version 2 of the Spindle Spinner which is pushing air down onto the spindle here: http://www.thingiverse.com/thing:486491
Can u correct the link? For me was important that the dust on my worksurface are not moved. Thats why i use the spinner to pump the air from my spindle to up
