I have uploaded two top sizes. The larger is approximately 60mm high and
the smaller is approximately 40mm high. Both tops spin very well. The
larger one may spin a little bit longer because it has more mass. I
printed these with 25% fill, 0.2 layer height, No extra shells, with
Support (Min angle 60 deg, No Cross hatch).<br>I have added updated models that have hollow centers (Version 3). These seem to spin longer.
