The author remixed this model.
I've corrected the scaling, orientation, and arrangement. To install these, you slide them from the left and right cheek of the SSL 2+ interface. Do not try to pop them on, as in doing so you'll risk snapping the top braces.
Size
Scaled to the correct size rather than requiring the user to accept a prompt to correct it in the slicer upon loading the model.
Orientation
Turned each part on it's side for optimal printing and strength.
Arrangement
Arranged the full print on a single plate.
