This is a new take on my [Counterswirl Top](https://www.thingiverse.com/thing:6022730). The original top had 2 arms twisting clockwise and 10 arms twisting counterclockwise. This has 3 and 12, which increases the mass and lessens the impact of small irregularities or alignment issues. It spins beautifully at any size from 100% to 55%.
UPDATE: I've added new STL and 3MF PrusaSlicer project files that include built-in supports. Combined with grid supports, they allow you to print both versions of the top vertically as one piece, which makes them spin a lot better. With updated speed settings, mine printed in about 2.5 hours.

To get the stem of the 55% to print well, I created a new version of the STLs with thicker stems. I also added GCODE to my 3MF file to drop the print head temp down to 177 at 10.50 mm. That worked really well, but I
