Quick and easy print. My desk has a bevel on the underside, so I stuck a strip of cork in there to help hold it in place.

I snapped the small threaded part off, so I modified the spindle part to be 1 piece and turned it on the build plate.

Nice design. Popped off the plate, cracked it loose, and it worked no problem. The fit on the spinner is a little tight, but I think it will loosen up as I spin it.
