I recommend you experiment with printing this oriented horizontal (like it would be when used) and vertical. From a stress standpoint, the top tab would be weakest when made horizontal and conversely the spindle would be weakest when printed vertically.
That said, this is designed better than other spindle designs I've tried. Improvements were made in the cross-section of the spindle, chamfers were added in several areas for stress relief.
One important point if you should decide to print vertically; turn the fans down to 11% when the large flat semi--circle area starts to print (I used Tweak at Z). If you don't you'll probably get the infamous "Heater Error".
