Increase gap for base-plate windows, thicken base

Use multiples of 0.4mm for base-plate acrylic window gap, and thickness
from floor to bottom of window gap.  This should hopefully help match
the MakerBot Replicator 2 print resolution.

Increase the width of the gap where the camera-holder rests in the
holder arms.  This provides more tolerance for printing variations when
fitting the camera-holder.
