Snap-Fit Design

      Disclosed is a low cost, low profile, snap-fit retention design
for plastic parts which is a snap together retention design that does
not require flex mechanism.

      As shown in Fig. 1, lightpipes 1 were added to door 2 covering
the op-panel 3 so op-panel lights 4 are more visible through door
than with current holes.

      As shown in Fig. 2, a molded-in high spot 5 on lightpipe and
corresponding low spot 6 in door, when snapped together, provide a
reliable retention method.  The design uses the elasticity or
resiliency of the plastic used for the door to allow enough
compression of the raised features on the door to allow the
depressions on the lightpipe to snap onto them.  At free state, the
unassembled dimensions at these points are at slight interference.

      Tooling is simple and low cost.  Design can be used where
limited space makes the use of more conventional 'flex type'
retention
mechanisms impossible.
