My LowRider is flipped from normal because of my room configuration. I probably forgot that at the time of the labeling the parts from my various remixes. If you need to rearrange them or ignore the labeling, it should be fine. Sorry for any confusion.
PS: in some cases, my parts are simply rotated normal parts. In other cases, they are mirror flipped in the slicer. But if I remember correctly, the only parts that had to be mirrored in the slicer were those pertaining to the bearing wheels.
