Recreated the base of NijDFish's great spinner design. It fit's perfectly on a 12mm wooden stick, second axis for spinner is now gone. :)

Print with the round area face down, support is needed in the inner-circle area.

Needs 2 M8 nuts and a M8-rod (as the original design). Slide one screw in the back, screw the rod in it and do a counter-nut in front. Now add the original pieces.
