Spacebar keys not rotated correctly

[Merlin04]

This is easily fixable in the slicer but spacebar keys are not rotated to put the side flat on the build surface, so if you try to print them without fixing their rotation the print will likely fail.

Yeah for spacebars I usually have to rotate them manually. I don't think there's anything I can do about it though because rotation value has just one default I can set and it obviously won't work for everything.
