Make sure to print in the same orientation as it would normally be when you open it in your slicer.  

For the “indicators” , I paused it right before the arrows started printing so I could swap the filament to the red filament and make it easier to see the arrows.  This can't be done if the part is printed on it's face, instead of the face facing up and using supports, (see the GIF / Photos below)

For the clamps, I used M3 bolts and allowed them to self thread into the hole.
